Gents,I have a set of Michigan main bearings, STD size for the 292 or 272 or (239). I would imagine you would only need these if you are turning down a 312 crank.
$65 total, I will cover the priority mail shipping to your door (lower 48 US). If you are international, we can talk turkey, no problem.
I can send a photo of the boxes/bearings if you need it, not too exciting I guess.
