Thanks Don and Scott. I thought about that too. You figure the stock MC was mounted to thin gauge metal on the firewall and brake pedal assembly. The adapter I'm using is the same bracket material that was used to hold the HB in most GM cars. 1/8" thick steel should be okay. If I feel it is flexing too much I'll use 3/8" or 1/2" aluminum stock. Another thing to remember is that there will be much less pedal pressure needed to apply the brakes. During a panic stop I bet the plate flexes slightly but no more than the stock manual disc brake setup.
This is still a test piece right now. I need to make a MC push rod for this setup
Been busy painting the dash the last couple days. Should have it cleared tomorrow. My SS lines should be here today so I should have plenty to do this weekend. :cheers:
