When I say fractional I mean the main bearings that used to be available from Toyota that were given a NUMBER 1,2,3,4,5 that were used to get a better tolerance on the crank.

See pic of the bgb


I have ACL duraglide mains that I have used to plastigauge and get a clearnce between the crank, and I have a couple that ideally need to be slightly larger, meaning I'd buy the 4, 5 numbered



The question,
