it's pretty simple. there are two bolts underneath the shifter and another bolt holding the linkage to the tranny. you might have to drop the exhaust b-pipe so you can have easier access. i ended up having to do this. other than that it's pretty straight forward. the bushing that connects to the tranny is going to be stiff, i had a hard time trying to get that sucker in there, but using my foot (literally) popped it in.
oh and you got ripped off if you paid $39 for the set. i got my energy suspension set for $19. does the same thing, and comes in a nifty red color.
