Are the frames the same?
Are the frames the same for a 1966 F250 and a 1970 F100? I realize suspension components and such are different but I'm talking specifically the frame and any holes pre drilled into the frame at the factory.
Anybody know?
ND?

1967 F250: The section modulus is: 3.89"
1970 F100: The section modulus is: 3.06"
Section modulus: Depth of the frame rails.

No argue with Bills numbers, they will be factual. I'm sure they mean something, just what I'm not sure in the big world of skeems and ideas.

I guess I should advise WHY I asked. I didn't want to to begin with due to the flack I anticipate receiving (and would recieve deservedly so...)
I want to do some modifications to my '66 F250. I'd like to have more of a custom than the standard truck. I'd also like to soften the ride a bit. I have a complete '70 F100 LWB and I am considering removing the body from the F100, restoring and detailing the frame then putting the '66 F250 body on it.
I know many purists are flipping out right now... But my question is WILL this work? Will the '66 F250 body bolt onto the '70 F100 frame?

Don't plan on working it hard. Haulin' the cans to the dump is the hardest it'll probably see. Going for the customizing. Just wanting to know if the cab, front sheet metal and bed will bolt onto the F100 frame.

Pdaddy, You are on the right track, these old 3/4 and 1 ton trucks will beat you to death. If you have a good motor why not move your sheet metal over to a 73-76 with a tranny that you would like to run and get power steering and disc brakes at the same time. I have done this more than once and usually sell parts that I don't use for more than I paid for the donor.
cs65 Please enlighten us, What is "depth of the frame rails is extremely important" in a conversion.
The body parts on top are all the same, and measurements underneath are the same.
thanks
John

Maybe this is my answer too...
Well Pacdaddy,
Maybe my answer is to do both 64 and 70! A 64 body with a later model undercarriage. Looks, performance, modern components, etc. Probably lots of non restorable 64's with crap or no drive train at all and lots of beat up 70's models with good drivetrains and crap sheet metal. Sell off whats left to make up the difference...

Of course I'm not saying that...
All I said is...the depth of the frame side rails is different.
What does that have to do with mounting a body?
Nada.

I dunno about you ...but IF Im going through all of this work and am gonna work the pee out of it I want the beefiest frame...I sure dont wanna inadvertantly put a smaller modulus frame under it.
Now knowing what its pourpose is...and knowing the body mounting was similar and it being confirmed theres no difference it doesnt make a difference.

I appreciate all the help.
SO -- I'd probably be better off selling off the '70 bumpside to an eager buyer and finding a trashed 73 - 76 with a good frame, huh? Did all 73 - 76 models come with power disc brakes, power steering? Heck, while I'm at it I could find one with a/c!

I believe power discs and steering were standard by 73, but there are a few out there without. Either is easy to spot.
Think in terms of what you want in the end, and look for a donor with that equipment. With a little planning you can find and upgrade your truck to what you want.
Be cautious of all them part numbers, you likely wont find them, because it will be engine, tranny, power steering and brakes that you will be looking at, and not scrapping rust and old mud wondering what part number this or that piece has stamped on it.

But power disc brakes were optional, so don't be surprised to find a '73/74 without power disc brakes.
1975 was the first year for F100's to have standard equipment power disc brakes.
1973/79: Power steering was an option on all models (and so was the AM radio!).
It was a different era back then. Most ppl bought trucks for work, not for play.
1991 was the first year more ppl bought trucks for pleasure than as work vehicles.
I don't think you'll find one part number on any parts after 1956.
Ford didn't put actual part numbers on parts after that year, only casting or ID numbers were used.
If you need front end parts like kingpins, the casting number is required, because there are several different axles.
One FTE member had a hell of a time with a set of kingpins he bought.
Why? Because 1965 F100/250's use a different axle than 1966/71's do.
1965 F100/250 king pins are one year only.
So are the kingpins used in 1972.
If you don't come up with the casting numbers off those axles = good luck getting the right parts!
