JE Piston question

[dsmtalontsi95]

I'm looking at buying a set of pistons off of a friend of mine who is a long time dsm builder. I trust this guy the most when it comes to cars. He is so detailed with everything he does. The question I have is do JE pistons have part numbers on them any where? He says that they are stock boar but JE doesn't have that option on there web site. If anyone knows please let me know. Thanks.

My .30 over strokers had the PN under the skirt on the pin boss.

Measure them? Any cheap caliper can measure .5mm difference.

Cool Thanks guys. I should probably get a micrometer anyway.
