WTB: Polaris Ultra 680 / XCR 700 Cyl Head Domes

Hello, I am looking for a set of domes for a Polaris Ultra 680 Triple. I have two sets but they're a mess. I think 4 of mine are cracked(from the plug holes in) One appears to be good but I am unsure about it. The last is, I believe a PSI head with nothing but an A stamped into it? It definitely looks aftermarket whatever it is.

So basically I would like to purchase a set of Ultra SPX or XCR 700 domes since I have PSI pipes. Obviously with no cracks and also no pitting. That is unless someone has a pair to match up with my good one. Also interested in aftermarket sets in the same condition. Thanks for the help!

Not sure if I want to use the '96 SP "C" castings or not. I have read its not bad practice to replace these heads when running the PSI pipes. I am keeping my options open for now though so if you would like to PM me a price for a set shipped please do so. Thanks!
