Pulling apart the rear since I am also cutting a 21in section from the truck, came to realize that the 2 piece drive shaft would not work in this situation and since the transmission does not have a standard setup where I can slide a late model shaft easily into place, I am at a quandary what to do next. It looks as though I would need a 62-63in slip spline shaft in order to fit it in there and from what I can tell that does not exist.
Thoughts.. would a 2 piece work there or by shortening the wheel base is that limiting my option? | | | | | Joined: Oct 2003 Posts: 5,152 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Oct 2003 Posts: 5,152 | Look under a '55 1/2-ton truck and see what it has.

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: Dec 2006 Posts: 197 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2006 Posts: 197 | Anyone have a 55 1/2 that they can take a look under for me? Maybe pictures?

My '55 1st GMC Suburban has an SM420 4-speed and a single piece open drive line. You need a similar setup.
I'm not likely to be able to crawl under it again before Fall at the soonest due to some medical issues.
