Parts' Casting Codes Question
Ok, so here's my confusion:
I have two front spindle assemblies from what i think is a mid '70s F100, but i don't know what year and I'd like to buy replacement king pins. I can read all the casting numbers off of them, but i can't find any explanations for this configuration of casting numbers. Here's what i have:
Group of four numbers ( I think the general part number): "9029"
Large single number on it's own: "1"
Small shield type insignia with the capital letter inside it: "I"
In a different location the code: "7-FB"
In another location the number "18" followed by a circle of thirteen dots that seem to form a clock with two dots at what would be 12:00 and a drilled hole at what would be 3:00.
What the heck truck is this part from ? What year is it from? Any help would be great.

There are no actual part numbers on parts after 1956, just ID numbers.
No spindle basic ID number begins with a 9. 9 parts are fuel related.
Large single number on it's own: "1"
Small shield type insignia with the capital letter inside it: "I"
In a different location the code: "7-FB"

Depending on the years, there are different ways Ford cast ID numbers on these parts.
First example
The ID numbers prefix begins with C8TA, for example.
That is followed by (depending on which side) -7 or -8.
Then comes the suffix which is one or two letters.
Right = C8TA-7-AA / Left = C8TA-8-AA
Second example
The ID numbers prefix begins with D2TA, for example.
That is followed by (depending on which side) 3107 or 3108.
Then comes the suffix, which is one letter, or two, or one letter and a number.
Right = D2TA-3107-AA or D2TA-3107-A3 / Left = D2TA-3108-AA or D2TA-3108-A3.
btw: Where did you get them? Junkyard or off a vehicle? Or did someone give them to you?
I HATE SWAPS, you wanna know why?
People make changes, do not record what the parts came from, then when something breaks, they cannot remember.
So...they waltz into the parts department, lay the greasy old crap on the parts counter and say...what are these for?
If I had a 5 bucks for everytime I went thru this scenario over 35 years, I could buy a new F150.
Sorry, but that's my opinion. How many of y'all have gone thru the same jazz, over and over and over again?

Bill & John,
Ok, i'm learning here.....you guys have been at this for ages. I'm starting to see the wisdom of your ways. The donor truck option is looking more and more logical in terms of time and hassle savings. I really don't want to make this into a nightmare parts puzzle.
You pegged my situation...I found a '66 that had been retro-fitted with disc brakes but the drag link and tie rod assembly was damanged so, I cut the spindles off. I knew the spindles would fit, but did not realize the difficulty i was getting myslef into. Now, I'd like to get new king pins and a drag link/tie rod assembly and I'd like to ID the spindles for future work and/or maintenance. There are no additional numbers anywhere on the spindles. I took them to a local dealer parts guy and he said that the 7-FB and 8-FB give them away as '75 - '79 spindles. He's not 100%, but he's 95%. Does that sound correct to you?
While we are on this subject, The reason I bought these, is that I'm putting together all the parts for a disc brake conversion. If the local guy is right and these are from a 75/79, then I assume i need matching years' tie-rods, drag link & ptiman arm?

Bill,
The more questions and phone calls i make....the more I'm liking the idea of pulling the entire front end off of one donor truck. Damn, I can build and remodel houses with my eyes shut, but this is whole new ballgame!

D5TZ3105A - Marked - D5TA-3107-FB
D5TZ3106A - Marked = D5TA-3108-FB
D5TZ3111A .. King Pin Kit.
Fits: 1975/79 F100/150 2WD
----------------------------
Why didn't I try and look this up before? It's a PITA, and I do not believe in guessing. AND there are TWELVE different spindles, six rights, six lefts: 1965/79 F100, 1975/79 F150 that's why.
1965 is all by itself, as is the king pin kit. 1966/70 is the same, as is the king pin kit. Some 1971's use the same spindles as 1966/70, some used 1971 only spindles.
Some 1971's use the same spindles as 1972. Some 1973's use the same spindles as 1972's, some are the same 1973/74...then there are the 1975/79's.
And all these are listed in front end parts charts in two different parts catalogs. NONE are listed under the specific basic part numbers of 3105 and 3106.
Now you know why I hate swaps!
And...if you think this is a PITA, look up a draglink for a 1970/72. There are FOUR different ones, as they are serial number specific. Not any help at all if parts have been swapped!
The ends of one type point the same way, they point opposite ways on another, then there's that before/after a certain serial number jazz.

About every thing under my chassis can be found by asking for 76 parts.
We might get Bill to do an upgrade one day to see the results, but I'm kinda doubtful it will happen.
I know I like my 66 a lot better with auto tranny, power disc brakes and steering and a few other upgrades.
After having done this for several years the donor purchase for parts or cab to chassis conversion is a preferred method. It helps with whinny parts guys. LOL

This swap mystery part question issue which Ive seen here umpteen times for various part is a good reason to keep things all original in my eyes...
As for front end upgrades...the entire front end 65-79 2WD is a direct bolt in. From what Ive seen and all the changes are adding a different proportioning vale due to dual master cylinder on later models and modifying the brake light switch mounting.
Dont ask me about 4WD front end swaps...to me...its a bigger pain...especially if you gotta have disc brakes...

It is simple. ignore the spindle as long as it is off a 65 to 79 f100 or f150 it will fit, purchase the kingpin for the year i beams you have. Ream the bushings to fit the pins and install it.
As to the tie rods the early parts can be used but the mounting boss on the spindle arm needs to be ground down to allow the shorter tie rod end to fit fully into the seven degree taper and allow the castle nut to seat correctly. You can use later parts if that is your choice. he geometry is all the same basic dimensions.
Part numbers will some times drive you insane and have zero meaning on the outcome.

How does one know what year the I-beams are? There are at least SIX different types: 1965/79 Ream the bushings to fit the pins and install it.

Uh huh. If someone needs to ID their I-beams as to what they fit, how can they do it? With a crystal ball?

Two different members a year or so apart posted they bought a king pin kit for their 1965. One king pin fit fine on one side, the king pin on the other side would not fit.
Why?
The answer is...that a previous owner changed one of the 1965 ONLY I-beams to a later model.
C5TZ3111C .. King Pin Kit / USE with I-Beam stamped: C5TA-3008-A or B (right) / C5TA-3009-A or B (left).
Fits: 1965 F100/250 2WD O-N-L-Y.
1964/72 Ford Truck Parts Catalog reference: Text / Section 30.2 / Front Axle Parts List 30.2A. Look this puppy up and see for yourself.

Bill, Dave & I know that many times things can be made to fit. I have no idea what the differences are in the parts mentioned above, but when looking at the front end there is no noticeable difference. IMHO
I'm sure issues could come up, but for the most part I haven't had any with parts. I think the parts houses eliminate many of those numbers that you have because they are no good for daily use. How many times do you post that a number has been replaced with a new number. I donno but get by somehow.

Looks can be deceiving, John.
For example 1967 F100/350: The dash, doors (and most of the internal parts), instrument cluster bezel, radio, heater, firewall, brake & clutch pedals, bracket under the dash they hang from...look just like the parts used on 1968/72 F100/350's.
They are not...all the parts I listed above are 1967 only.
The king pin kit & the I-Beams used on 1965 F100/250's are 1965 only. There is no part number update, no before/after serial number.

Bill is spot on with the kingpins...I've got a 65 and looked the kingpin kit up...its a bit confusing but if you look further in the parts books theres a few specs as I recall on the pin dia. among other things.
But if you know the year of the truck the parts came as well as the model then you are miles ahead of the game...if you swap axles with spindles you have the axle casting numbers and know the year of the axles and thus the correct kit can be easily(usually) obtained.

But, if you go to basic number 3105, the spindle specs are listed.
If you go to basic number 3115, the king pin specs are listed.
The last two days I haven't done much of anything here, cuz I've been too damn busy typing countless P/M's back and forth with the little weasel (NOT my idea) cuz he's stuck as a fly on flypaper, has the(73/79) catalog, is clueless (or too damn lazy) to figure it out. He wants me to give him all the info. Uh huh, yeah right.
Now you seem to need help...and you've had the 1964/72 catalog for years.
