My local shop (and most, from what I hear), do a shim exchange. Bring them the shims that you wouldn't be using and exchange them for the right size. I think they charged me $8 for two shims last time I adjusted the valves.How do you guys get the proper size shims when you do your own valves? Do you just go to the dealership and buy the 8 specific sized shims you need after measuring? Or is there somewhere online that rents the shim kit?
