[DeTomaso] Booster fixed

[JDeRyke at aol.com]

Sean, the only problem I've ever had with their conversion was related to 
GM's cost-cutting design: the GM air valve that protrudes from the backside 
of the booster (through the firewall under the dash) is brittle plastic, and 
the assembly can be cracked either in shipment or as a result of trying to 
fit the slightly larger GM booster into a tight-fitting Pantera by yourself. 
Since yours worked, you did it right; others may not be so skillful (like 
me!)   But the larger stepped master cylinder and the dual vacuum booster also 
work exceptionally well in our Pantera. 
Note that there is an approximately 2-lb residual pressure valve built into 
the master: its a thick black plastic washer-thingy with a circlip, a 
ball-check and a short coil spring hiding under the reservoir attachment to the 
aluminum casting, if you're interested in removing or modifying it. In any 
case, don't add another one to these brake assemblies! FWIW- J DeRyke
