Black water tank vent same on Streamlines and Airstreams?

[JeweloJalopy]

Hey gang,

Does anybody know if the gasket that seals the black water vent is the same on a 1966 Streamline and an Airstream? I know mine is leaking (shocking) as I can see water dripping off the vent stack when it rains. I'd love to have a replacement gasket in ha before I crawl up there and open things up. But I might have to then buy a gasket afterwards.

Thanks!
Ian

The plumbing vent line is about the same size on most all TT's. I bought some retro looking metal pieces from VTS for the last trailer. A decent sealant was my only "worry" (can't remember which one, but the A/S folks use it for large areas like this).
