I know it's been some time since I've posted here, but I've been working diligently on my 1950 3600 as spare time allows.
I reached the point that I was ready to drop a driveshaft into my truck and was resigned to the idea that I would have to have one custom made. I was pleasantly surprised to find that a 65-68 Chevy Impala driveshaft will fit nicely, and cost me a whole lot less on Ebay. The yoke is a perfect fit. The only change is the rear universal joint has to be changed to a crossover joint (part #348 from Napa I believe).
I just wanted to share this info with those of you who are looking at dropping a small block into a 3600 AD truck. FYI, the driveshaft is 62" center of U-joint to center of U-joint.
Good luck, and thanks to The Bolt. This board has been a tremendous help to me over the last 7 years.
