Through a little searching I found this is not a truck transmission, this has the slip yoke tail shaft. What I've read the truck tail shaft had a yoke mounted on the output. I'll hit the salvage yards and find a driveshaft that has the correct yokes so I don't need special u-joints and have the local speed shop shorten it if needed. Here's the transmission with the one and a half inch section in between the gear box and tail shaft.
