Thanks for all of your help, guys.. I appreciate it. As far as those bearings go - is one really SAE and one Metric? Aren't both bearings usually metric? I totally believe those to be correct, I just find it a little odd that one's metric and the other isnt.

I'll order those up and pop 'em in. I can use the 300°F oven trick to swap bearings on an aircraft engine, right?
