So, how does one handle the VIN when swapping the cab and interior from one truck to another?

Specifically, I've got a 77 F-250 4WD 4-speed that has a ratty cab, and I want to move the incredibly-good-shape cab off my "parts" truck, a 77 F-250 2WD Automatic to the 4WD truck. I know I'm going to have to accommodate the shifter/4wd sticks, but how have ya'll handled "swapping" the VIN from the original cab to the new cab?

 

is it screwed in? or riveted?

 

The tag on the door isn't "legally" a "VIN" plate, it's a warranty plate.
Legally the VIN stamped on the frame is what's used for title purposes. You can transfer the plate on the door to the new cab. Marti Marti Auto Works - Concourse Quality, Hobbyist Price has the special rivets to install the plate. You could also order a new warranty plate and cert. sticker. Marti's work is top notch.

 

I'm more talking the VIN tag on the dash, as seen through the windshield...

 

Fords didn't have dash mounted VINs untill the 1980 model. Before 1980 the legal VIN is the one stamped on the frame.

 

Oh.

Maybe I'm dumb - I thought there was one visible through the windshield in the typical spot...

 

Nope, not dumb just unfamiliar. You'd be surprised how many DMV people look for dash mounted VINs.
