The Mancini Superformance #9383 works. Noticed rear leak on Duster the last race and it got really bad with dinner plate sized puddle on the trailer floor from starting motor to put the car in garage. I knew this was coming as I had ordered the Kit at the end of the season and am now getting ready for New Years Day Opener. So I installed the Superformance Kit from underneath (yep, as much fun as you can imagine) and crossed my fingers. No 130 mph runs yet but 1st impressions are promising. Survived extended idle and two 5200 rpm Tbrake stalls. Clean and dry. When it stops raining for Testing or New Years Day I'll confirm it holds up under race conditions. For the moment the vibe is good.
