A few months ago I did some work on a transmission for my Spider, including the 1st gear synchro modification. The only half way decent set of circlip pliers that I could find were Craftsman, from Sears. They were just barely adequate to remove and re-install the couple of big snap rings I needed to R&R; I don't think they will hold up to doing another snap ring. Removing the snap rings is hard, but re-installing them is almost impossible. If anyone has a trick, I'd sure like to know.
I have a friend that I'm helping with his Spider, so I have another transmission in the not too distant future; I think I'll track down the local Snap-On truck and see what they have.
