i have a NOS ATE brake booster but have no idea what it fits. it is a T51 with the ATE number - 3.6122-1706.4 it looks just like the one on my 72 Ascona but that rod isn't right. this is one of the leftovers from the time my dad was in the dealer, the only problem is he didn't a short stint in a Porsche/Audi dealer. he also worked in a Fiat dealer for a while, all during the last half of the 70's. so if anyone can ID this for me i would apreciate it. this doesn't fit my Opel so it will go up on Ebay somehow.
