I need to purchase a set of main & conrod bearings for a 20V 4AG from toyota, I have the part numbers, but what exactly do the "Mark 1, Mark 2, Mark 3" designations mean? I know that for pistons they are slight diameter increments to match each bore exactly, but how much difference is there between each 'mark' with bearings?
