You will either need the order/job number, from which the can make a new one or simply send them the damaged one. Email them they will be able to tell you.

Im guessing they will be customs. You may have to send one to JE as a sample.

If you can find out the original purchaser, they may have an order no. that JE should have on file.

Otherwise try Peter Z from the US.

Good luck.

Hi - does anyone have a part number I can try for JE Pistons? I have damaged No.1 piston (JE) in my race engine but unfortunately haven't yet been able to ascertain the part no. (I purchased the engine second hand some years ago).
Pistons are:
Flat top, with valve reliefs
Bore 78mm
18mm piston pin (full floating/circlipped. Brass bush pressed into conrod)
1mm top ring/1.2mm 2nd ring/3 piece oil control ring
Engine is A12A FWIW

Any and all suggestions gratefully received!

Thanks
