I need a new threaded adapter (1-1/8" scat tube) that screws into the front of the round gold pressurization mixer box/valve assembly. I've already spoken to Lancair and their vendor without success. 

Justin,

Don’t know if you have a different mixer box assembly, but pretty sure my scat tube adapters are pressed/then welded into the “coffee can.” This should be relatively easy for a local machine shop to repair/weld up for you, but it will destroy the nice finish on the mixer box.

Send a picture directly to me if you’d like and I can advise further…
