Hi all, I am looking for some help decoding a 1990 Ford F series door tag from a truck that a friend has offered as a parts truck for anything that might be of help on my '66 F250. That said, the info I do find, is not that clear or consistent so I thought I would post the tag here and see what the fine folks in the 1987 -1996 forum might be able to add. Thanks in advance. - Matt

 

What is not clear or consistent?
VINs are very precise
1FTHX25HXLKA72356

If your talking about part swapping between a 66 and 90, well yes, your going to get "nothing fits or is the same" to "anything can fit, when you make it".

1990 Ford F-250 HD Supercab Styleside 155" WB, 351w, C6,

 

Hi wwhite, thanks for the decode! Could be that I was not using the best website for decoding such a new truck.

I know some of the data from looking at the truck.

What I was most interested in is if the disk brakes might work? I have a late Camper Special, and it has the same spindles as the '67 and later that they used for the disk brakes, so theoretically I could just get the backing plates, calibers, and some new disks with hubs, and bolt everything on. OK, I know it will take a bit more than that to finish the job, but it's a start. That and I was wondering if the rear axel is also a Dana 60, and what ratio it might have.

Outside of that, I was not thinking to grab any other parts, as my truck is pretty complete and running pretty well with the motor I have and while I would love to upgrade my transmission, I might also consider just swapping for the same type and weight class diff with lower gears, while keeping my diff on the shelf for originality.

Anyway, thanks for your help, and if you or anyone else has more to add, I would be thankful.

 

I don’t have a decode link, but from researching my 95 F250 here’s what I think you’ve got:

F250 4x4, based on the GVWR of 8800, a 2WD is 8600. H in 8th position in the vin is 5.8/351W. Trans G code transmission is a C6, preferable to an E4OD imo, just read all the threads on here about electronic issues with those. Axle code 39 should be a Sterling 10.25” open differential with 3:55 gears. Will have drum brakes on the rear. Completely different platform from your 66, so be prepared for some fabrication if you’re swapping things over. Might need a bell housing for the C6 depending on the motor in your 66.

 

That just means there are thousands and thousands of these trucks still on the road with E4OD's that a lot of people don't know there are codes stored to help them find a fault with a sensor or wiring issue.
When a C6 trans blows, you don't typically hear about it, because most people know what to do; swap in another trans, and there are only so many questions to ask about those, like how to adjust a vacuum modulator or something. Stuff that's easily searched for.
The E4OD is a far more advanced trans over the C6. E4OD/4R100 are built on the C6 architecture. You get a locking converter and an over drive gear. Wherever they can physically fit, in place of the C6, you should want one. Don't let multiple questions about electrical issues scare you away.

 

Motohowie & FORDF250HDXLT, thank you both for your input and feedback. I do believe the truck is only two wheel drive, and I also believe the motor and transmission have been removed already. It does have a nice service bed on the back that I think my friend plans to take off, clean up and put on Marketplace. The rest of the truck will go to the scrap yard, as it was in an accident some years ago and is just sitting in the wood taking up space. The the damn full is a bowtie man...OK, that last part is true, but a finer human being you will never meet.

As for my old '66, a previous owner has changed out the motor and transmission to what I believe is a 390...yes, I am aware it also could be a 360, and a C6 transmission. Truth is, I would love to put a Ford AOD in and get the extra gear, but preferably stick to an earlier model before the electronics came into play. That way I can use my original analog speedo cable and not have to have any kind of ECU. I know that the AOD, is not rated as high power wise as the C6, but for my application, it would do just fine.

Any thoughts about the brakes? It sounds like the rear diff is not a Dana 60, so I won't be bothering to try and get that out. The power steering is also different from what I can tell, so at this point the brake calibers might be the only thing worth tackling. Unless, someone with more experience (which will be nearly most everyone at this point) can steer me away from trying to get brakes from such a late model 250.

Thanks again folks...it nice to feel welcome and get feedback on this side of the year fence.

 

Dang, that's a shame. Being a 2wd, I bet her frame is solid and real nice. I felt bad about scrapping a front half of a pristine (2wd) one myself though; the rear half lives on in my 4wd F250. Maybe you can convince him to list the truck for sale for the clean frame? Someone out there locally may be looking. I happily payed $500 I think it was for mine. Would have been willing to pay more if I had too (of course I still had to pay a truck welding shop to install it, but still). Saved my truck for many, many, many more years probably. That one could help save another.

 

The Ford AOD transmission was only ever produced with the small block Windsor belhousing and it's integrated not detatchable, so you will need a different engine or an adapter plate to mate it to the 360/390. These were all mechanical transmissions with a speedo drive cable off the tail housing.. 2wd version anyway. Do not confuse this transmission with the later computer controlled versions that are referred to as AODE or 4R70W, they are not interchangable. The mechanical AOD was used through the '80's and into the early '90s in cars and light trucks, the later versions had updates that greatly improved durability and there are now lots of aftermarket performance options that further increase it power handling capacity.
Is your '66 2wd and if so does it have the TIB independent suspension? That would be an early version with king pins I think while the '90 truck has ball joints so the spindles are not interchangable, but you could potentially swap over the complete suspension to gain disc brakes. The '90 F250 has 8 lug wheels... 8x6.5" bolt pattern, I don't know what a '66 would have.

 

FORDF250HDXLT, I am pretty sure it was a 2x4, and it was in an accident, so the frame might not be as solid as one would hope. I have to go back and take a look at the photo's.

Conanski, Thanks for your input, yes, I forgot to mention in my thoughts about the AOD, the need to use an adapter plate for the FE motor. Thanks for the reminder to double check whatever I end up finding that it is not the later AODE. Otherwise, lI think it would give me a good overdrive that would meet my needs as my truck is purely for fun and I won't likely be doing any standing burnouts, or pulling any 7k lbs trailers.

As for the brakes, I seem to think that I read somewhere that up to '87 was a possible bolt on, and it sounds like after that there were enough improvements that I will likely be better off looking for an early donor for my "upgrade" needs.

Thanks everyone for your impute, and keep those late model trucks on the road.

wwhite, thanks for the link...I had forgotten about that one...I am actually the last one to post on that thread. Now I wish I could find the link that gave the spindle part numbers but I guess it actually is not that important right now.
