Oh I looked but I couldn't find it. i finally found the Code3 instructions for the gap but I didn't see anything about harsh engagement or thickness of the shims.

@NeedsWings I did not damage the pulley, fairly sure. At least the springs look fine, backing plate seems to engage properly and the new bearing is all the way in and seems to be seated correctly. Everything seems fine. I think this one has to do with the right gap, but my shims are bent from bad storage (the OEM shims) and so I was trying to find out what the original size (diameter/length) as well as thickness is to have new ones made.
