Thanks buffalos
 
i had a guy who used to work at a machine shop tell me to look for the 060 and 040 sizes he said to be safe but he said i would need to get it welded and grinded down but i don't know how safe that is new crankshaft are around 800$ new i'm just wondering why only one bearing would wear that bad maybe oil starvation, not enough oil getting to the rear?
