Hello I am in the process of doing a restoration on a 1986 Chevy C20.
I am trying to find out if a 1984 Chevy K10 cab will fit on my C20 frame I found one for a good deal but I don’t want to buy it until I know if it will fit or not.

Thank you in advance I appreciate the help

It should, you need to usually at worst either find a tunnel cover that doesnt have the openings no longr needed or you close up some. the 2wd can have a lower floor in center

The only issue is which transmission you have. Trucks with the 4 speed manual trans has a removable hump cover. Automatic trucks have a solid floor. You can cut the floor to fit the 4 speed, but the cover mounting bolt threaded inserts will not be there.

Air conditioning cabs have different holes in the firewall than a truck without AC. Easy fix either way
