Sorry I was not clear. There have been some conflicting information about whether B body Mopar brake boosters are a replacement for the Stude ones. In the trivia section, it was stated that the "hemi" equipped cars used the same 8 3/4" brake booster. This booster, like Avanti boosters, are hard to come by. In a later post on this forum, it was claimed that the readily available 8" Mopar booster works. Most of the posts on the Mopar forums indicate that the hemi boosters are not interchangeable with other mopars and versa visa.
Just trying to find out if the readily available B body 8" Mopar boosters work on Avantis.
