I've read that finding EDPM o-rings for the PDWA in a TR6 is a sttruggle. If a source for these parts hasn't been found yet, try these folks. They have a huge inventory, and better yet, you can buy by the PIECE. In this case, 10 cents! (plus $9.50 S&H, of course)

Someboby let me know if sourcing these is no longer a problem. Thanks.
