If you are interesting in selling the 292 send me a private message. I am in the Rome, Ga area and I do have an extra perch. Are you planning to keep the 4speed if so I have the V-8 bell housing cross member. If you swap to an automatic transmission you will have to remove the cross member that the parking brake linkage is connected too. You can however use the 66-68 set up. 66 was the first year that a turbo 350 was offered in trucks. The 63-65 parking cable-cross member set was in the way of the transmission tail shaft, therefore 66 was different then 63-65. All that said with assumption that GMC's where the same as Chevrolet. You will probably have to get a drive shaft made.
