OK, she's all nice and clean now, reinstalled. I read and followed the beer can shim discussion, and sadly, I am such a snob that I've been drinking beer from bottles. I didn't have any beer cans, so I used an aluminum catfood can instead.
In shimming it in, after I tightened it down, I pulled out the shims. One was pretty tight.
Should i go back and redo, or will there be enough clearance on the tight one that it should be OK?
