I found 2 pairs of -.030 +.015 inserts for the front and center mains at Red's Vintage auto parts, thanks to Red Hamilton and Marilyn. I'm running out of folks to ask, the few who understand what I'm looking for don't seem to even want to talk to me about it.
I'm close - If I can find a rear main bearing, I can grind up another crank and I have it solved. Anyone have other sources of old OEM parts you are willing to share?
