I have an 80 k-10 with rotten floors, cab corners, and rockers. I can get a cab from an 85 c-10 from a buddy for a little bit of nothing. My question is and I think I am right in thinking the cabs are the same except maybe the tunnels. The later cab has the cowl grill on the cab and my 80 cab has the cowl built into the hood. Can I do a fairly painless swap or is there something Im missing. I dont mind cutting and swapping a tunnel when the new cab has perfect rockers and floors, which is amazing.
