I have looked at black dragon, and MSA, would Ztherapy sell those separately?

Probably. Have you called them to ask?

MSA has lots of stuff not in thier catalog. Same for Black Dragon. Like Arne says, give them a call.

Z-1........There's several sets on ebay right now........The best price is buy-it-now for $12.65. Look under DATSUN 240Z in ebaymotors...item#25031/17599744. He should be able to mail it in an envelope with 2-3 postage stamps.

Which air cleaner gaskets are you searching for?

The ones that go between the SUs and the base of the filter holder or the one that seals the cover to the base of the filter holder?

I believe I have both, new, OEM.

I need the ones that go between the SU's and the filter mounting plate. They actually sit against the SU's

We found some. $4 each. As you can tell, we don't have a lot of call for them....
