In November,I backed out of the garage for a morning drive and found the brake pedal was not stopping the Coupe as usual. The big fat OEM brake booster almost touching my center DCOE40 Weber carb was not working. With 2 annual car shows coming up, I drove very carefully to them w/o full brake power. And I bought the only restored Tii booster Hal Boyles had in stock. This was the perfect time to get clearance between the booster and the side-draft carb. My mechanic was able to install the booster w/o draining the brake fluid reservoir. The brake pedal pressure to stop the car is slightly more than before. Now I have clearance for an air flow meter to measure each Weber.
