Since I do not have an assortment of shims to chose from I opted to buy a shim punch and punch out my own shims. This worked OK to a point. The job had to be finished before I could order shim stock any thicker then .002" and I had to make do with that when I assembled my injectors today. My wife needs the car for Saturday.
The job would have been easier If I had had some more thicknesses to choose from.
The outside diameter of the shims are close to 7/16.
The shim punch will punch up to .010" of hardened shim stock and I got new as a "Buy It Now" on Ebay $50.
Also another fuel injection company Diesel KiKi makes thin shims for their copies of Bosch injectors that also fit Bosch. Since it was 25 years ago I have no idea what they would cost now.
I added this pic. There is a metal bolck with holes under the orange paper tag.
