Ok I have a 1990 F150 Ive put everything interior body and all off a 94 on the 90 frame , except the cab , does anyone know if the dash out of a 94 will work in a 90 cab and mount up right?

 

It will physically bolt in but there may be issues depending on how much of the '94 truck you used. If you swapped all wiring then there won't be a problem, but '94 uses an electric speedometer and the '90 uses a mechanical one.

 

Lol like I said in another thread you replyed to I have about 3 projects going on right now , on this one i used the doors the front fenders and front end and bed off a 94 , the only thing i didnt switch out was the cab and the wiring , the motor and trans is out of it right now because im converting it to 4x4 and i had a good low mileage straight 6 motor out of a 94. I just bought a 95 F150 for parts , and was planning on taking the wiring harness and dash out of it and putting it in the 90 when i dropped this straight 6 in it from this 94. Lol its a big mess man I know , but you are sure the dash should bolt up to the 90 right?

 

I would have to say 99% positive.
