Not sure if there is one on an LLY, I believe the discussion is about a gasket for the LB7 mouthpiece flange where it bolts to the turbo. Its not clamped like the newer models.

I'd just get a new gasket from the dealer for a couple bucks if yours isn't reusable or make one like mentioned.

Not familiar with 1132, but I just used a thin film of silicone sealant on mine. Did not want any gobbs of it loosening up and going through the turbo.

Thank you to all of those who have served or continue to serve our country to keep our country free!
