Who makes a booster to fit 81 Camaro m.c.!??

[80Camaro]

Everyone seems to think that their 11" booster fits 70-81 Camaros... but they don't. I have a new Delco alum master cyl that I want to use in my '71 but the Tuff Stuff booster hole is too small. Who carries a new booster made for an '81?? I have called just about everyone!

does the booster not fit the firewall or the master that you have doesnt fit the booster? can you post a picture of the problem areas? Part number for the master too if you have it.

The diameter of the mount hole in the booster for the master cyl is too small... by a long shot. AC Delco part # for master is 18M172 (1981 Camaro). The 81 is different because it is the first year for the aluminum body w/plastic resevoir. The booster center hole has to be 2". The previous was about 1-11/16"

I know they have one for the 81 TA 4 WD but it is a dual diaphragm that give more assist-why they decreased pedal ratio on those cars. I had to replace the one on the 81 TA a few years ago.
