If I am remembering correctly, swapping just the center section should be no problem in either case, you will end up needing a driveshaft, and a transmission for an open drive setup, hope that helps. | | | | | Joined: Dec 2004 Posts: 1,897 Shop Shark | | Shop Shark Joined: Dec 2004 Posts: 1,897 | 4.11 to 3.90 is not much of a change. Are you swapping for an OD transmission? | | | | | Joined: Jan 2008 Posts: 4,961 'Bolter | | 'Bolter Joined: Jan 2008 Posts: 4,961 | Do you have a 59 parts truck, or do you just have the rear end. If you have only the rear end, you will need an open drive shaft transmission and a drive shaft. Whatever works on your Chev will also work on the GMC. | | | | | Joined: Mar 2008 Posts: 10 New Guy | | New Guy Joined: Mar 2008 Posts: 10 | On this same topic - anyone know what late model pickups make a good donor for a rear end? I know that Mazda, Nissan and Isuzu have the same 6 lug pattern, but I have no clue on the rear end widths or the gears in them
thanks!

It is very close to the orginal width and it has the same 6 lug pattern as the original. We just needed to weld new spring pads and, of course, change over to an open driveshaft transmission. For what it's worth... | | |
