USPS damaged the gaskets
Came in USPS bent , I didn't use them and threw them in the trash after JP Cycle refunded me. I used my old ones and added gasket sealant to them.

packaging
The gaskets worked great, no more leaks, however the packaging could be better. The gaskets are metal and shipping them in an envelope makes for bent gaskets and crossed fingers hoping they won't leak.
