I use the same method Dave D. uses, hold the shim on the side with a 
pencil magnet and press it in the cup with a small tipped screwdriver.

I think you're in for some more fun when you get to the ZZR. I think

you get to pull the cams out. Better get it right the first time or the 
cams come out again. Just when you thought it couldn't get any
