SL/R107: Please identify pistons
On the inside is a MB star, one skirt inside has AO31 (AO51) and AO61 and the other skirt inside has 96L26 cast in. Also Mahle is cast inside. I am assuming the AO31, AO51 and AO61 are the machines used in the casting.
In the piston crown in very small stamping is 710, 117, 8696
Can anyone identify these pistons? I am guessing they are either 500 or 560
