Rotary valve oring

Hello everyone. I need a new rotary valve oring gasket for my 1976 Skidoo RV340. Can they still be purchased new?
Do they share the same oring as any newer rotax rotary valve engines?? Any help would be appreciated. Thanks.

I called my local dealer today and found out that it is obsolete.

Don't feel too bad about the dealer......probably have obsoleted the stuff from 2015 by now.

A little more info on the 0 ring you are searching for.  Are you looking for the large one that goes  between the outer case and the very large rotary valve  cover?  The aftermarket kits used to have that one included.  A tad thinner than OEM, but worked.
 
Or are you looking for something else? I believe there are a few other locations  on the rotary valve shaft  where O rings  are present.

Hi there. Yes it is the very large one for the outer cover. I ordered gasket kits from two different  places. They came with everything but the oring for the cover. I was told it is a dealer only item. Well not anymore lol. I have no idea where to source this item. Thanks.
