I want to go smog (CA) exempt by swapping a Chevy 74 1/2 ton cab w/title to my 80 3/4 ton frame. Both are 4W/DR. Will this cab fit on my 80 truck?
 
If you put your ’74 body on your ’80 frame you will still have a ’80 truck and not escape bi-annual smog inspections. The registration and smog inspections are based on the frame year and VIN, not the cab.
 
Actually, '74 trucks did NOT have the VIN on the frame, so the DMV goes by the cab VIN. You will need it in TWO places, however, for the inspection, so the doorjamb and glove box or the like should match.

The '74 cab and '80 chassis will bolt right up with no problem, I did that swap several years ago when my '80 cab rotted away. Good luck!

...but the '80 frame will still have the VIN on it. Also, more than just a VIN on the frame is used to determine what year it is. What he is doing is called a "Cab Change" and there are specific procedures to follow. Call you local CHP VIN Officer and find out how he wants you to do it, if you want to keep it legal!
