Replacements for GM piston 14093990?
 

What are some aftermarket replacements for GM piston part number 14093990 ?

Those are the Hi-Limit pistons for a 1992 5.7 from a pickup with the Z71 option.

I can't find anything online except a few crazy priced NOS pistons. Seems nobody has a searchable interchange or cross reference, not that I can find.

I'd think Sealed Power and the other manufacturers and vendors would want to have a database with all the OEM part numbers cross referenced to aftermarket replacements.

Normally when one piston needs replacement people replace them all, in which case you can go with whatever piston you want. If your replacing a single piston, I'd get the expensive oem replacement to make sure you don't throw the balance off too badly.
