At least that is what the micro fish says.
Get the shims from an alignment shop, or better yet leave them out and let the alignment shop put them in. You will need an alignment when you are done. I hope there is a shop close to you, or you have a trailer. Driving any distance without an alignment can F up your tires bug time.
There is no "set" number of shims, it all depends on the car and the parts.
