Hey guys, I've got a 1986 C10 that I'm looking to swap a 5.3L into. It currently has a 700R4 which I am going to keep, and I want to mate the 5.3L to it without moving the transmission or crossmember forward.

It seems like I've read every C10 swap thread, but I can't find anyone who has used the 1" setback mounts. I did find one member here with a K10 suburban who used the 1" setback, but I'm not sure if the C10 is the same. Does anyone here know if I can use the 1" Carshop mounts in a C10 and clear the firewall?
