How bad can it be?
OR...a crazy thought: get 1 .010 under bearing, chuck it between 2 caps and run a cylinder hone in it until the plasti-gauge reads spec on the very slight undersized buffed journal? My old 82 Mazda manual states "any scratches on bearing journals should be dressed down with a stone..." I guess they dont think much of a small scratch? These scratches are probably small enough to dress down and run STD's
