gm is the man when it comes to ultimate resourcefulness. Economical and safe, using a lot of on hand material. The guy you want in your club when your stranded somewhere!

Definitely buy the engine hoist. I have saved my back many times. It does a great job picking up the trans, transfer case and cross member assembly, and setting the whole ball game on the bench. (something I seem to like to practice)

gm, whats the capacity on that boom at that length? It seems to handle the load well.

Chuck, the roll pins are what is used today. Just make sure they are HARDENED roll pins and the correct size. Roll pins are sized by the diameter of the required hole, i.e. a 1/8" roll pin will fit tightly in a 1/8" hole. No China allowed. That's whats in mine (hardened roll pins). The shift lever spring can be found. If it is pitted, it will eventually break. Here is a good source, https://www.willysjeepparts.com/T90_..._And_Parts.htm
