Diamond Pistons 21500-R1 !!
Unfortunately rebuilt my L83 and was trying to find a drop in piston. Having no cylinder bore damage i decided i didn't want to send to a machine shop and do balancing. Found and recieved the 21500-R1 pistons from diamond and was 10grams lighter than factory piston. Dropped them in and no issues.
