I have a 1977 K10 Frame with a MINT condition 86 Cab. I know I have to use the cab mounts for the 77 but I need to know how the fenders and radiator support and such are going to work. Any information will be appreciated. We have a 86 hood already I know they were changed as well.

Thanks!

I had to oval the holes in the 84 core support I put on a 78 frame. Depending on the year of the core support you may have to do the same. Everything else was same ish.

You would use the bushing set for the 73-80 frames. They have simple round holes on the frame mounts. On the 81-87 they are round holes with flat sides.
