i just got my mcleod street twin kit. what else shoud i change while changing the clutch. and where is the best place to get it??

 

Change the rear main seal and the pilot bushing. You can get them at AutoZone or Murray's. You could get the RMS from the dealer, but not the bushing. GM has phased out the bushing in favor of a roller bearing. I have heard some horror stories about the bearngs, and I went with the bushing myself. Make sure you have an alignment tool if your kit didn't come with one. You can pick those up at an auto parts store as well. Do a search, the street twin is super popular and lots of people have asked similar questions.
