Forgot to mention that the driveshaft from a 62 Suburban fits right up to the stock 3 speed, but I had that one chopped for my 3 speed w/OD. In other words, to do this right, you need two specialists: 1) A spring manufacturer that does vintage springs and 2) A Driveshaft machine shop that can cut you a decent driveshaft. Very important to get the length of that driveshaft correct. You need at least 1.5 inches of slack in the shaft so when putting weight on the truck, it doesnt bottom out. Trust the professional you choose for that one. Hope this helps!!
