Any recommendations of one to use (brand/model, cost and were to purchase)? I ordered disk brakes (Baer T4 front and SS4 rear) for my '72 Chevelle and they recommended I use at least a 9 1/2" dual diaphragm booster. Well, I haven't seen a 9 1/2" (mostly 7", 8" and 9" dual diaph. boosters). I have a Vette 4 wheel disk master cylinder that I'll be retaining from my old front/rear 11" disk brake setup. The booster I currently have is an 11" single diaphragm (Baer said to ditch that one). Let me know what y'all have used. I like for it to be a bolt-on type booster (no modifications to mounting it, etc is preferred). Also, are there other parts/pieces that I'll need to install the new booster? Thanks ahead of time for any info/responses.

Not sure how the 79-81 Trans Am 4WD factory 9" booster would fit the firewall.
