I'm about to send all of my stuff off to the machine shop for measuring and machine work. I'm also looking into bearings and what is best.
I recently stumbled across via a internet search a brand of bearings called ACL Bearings.
I think they are Australian? There's only a few posts on here that mention them, but non Porsche people seem to love them, particularly Subaru people.
Unfortunately they only seem to make rod bearings - no mains, for the 911's. But they are apparently the bearings that take the real beating! Anyway - they are worth looking into! Not expensive either... $130 AUD for the set.
