Am in need of a set of U piston pins (AC engine). NOS oversize would be preferable, but at this point....

I have gone through all the dimensional catalogs of piston pins and have not come up with a suitable interchange. There just is not stuff with a 3-5/16" pin with length over 4". What have others done?

Also, who ended up with Norms stuff???

Pfouts bought norm out. Good luck. gave him a list a few months ago haven't heard back and he went dark. Its really difficult to find parts for u/m when he appears to have the corner on the market
