I'm changing the Rod Bearings on my '86 4x4 pickup. I need help determining the size bearings I need (Standard, 25 over, etc.). My Haynes manual says to determine the size get the letter off of the rod bearing cap (A, B or C). The letter on my caps are B. What the manual doesn't tell you is how this carries over to the size. I'm thinking since mine is a B it means 25 over. Any help here sure would be appreciated. The service dept at the local Toyota dealer was clueless to what I was talking about. They only order them as A, B or C.
