Does your car currently have a bracket on the firewall that the booster is attached to and the articulating linkage is outside the firewall?? I just did a '69 Charger for a booster and the replacement ones have too big of a bolt pattern to mount to the existing bracket hole spacing and the actuator rod's hole is too big for the stock linkage pin. Pain in the a**......but it can be modified...

I have a customer at this time fighting the same battle. This is a 70 B-Body using the power disc brake conversion kit from Right Stuff. Everything fit wells with the exception of the lines coming up the inner fender to the master cylinder. The customer has been on the tech line at Right Stuff twice trying to determine the fix. The supplied brackets is wanting to lift the booster and master cylinder too far forwards and high. There is no way that I am going to ask the customer to modify the firewall. For everything else to fit so nicely, the owner is completely dumb founded. Has anyone else had a similar issue with this conversion kit? Thanks for any input.

I bought the repro bendix booster and M/C from Dr. Diff. I have a 70 GTX that was originally a power drum brake car. The only mods made are opening up the I.D. of the bracket by approx. 1/8", when it fits the booster register, just take it off the booster, place it against the firewall and mark the firewall with a Sharpie to match the mods made to the bracket I.D. I used a die grinder with a carbide cutter to open both holes, it took about 10 minutes and you will never see it. The repro M/C mounted up perfectly and the lines are at the correct height. It was easy and straightforward with no problems and works perfectly. All of the original brake pedal linkage hooked right up. I am pretty sure that there is only one repro Bendix being made, I bought mine from Cas(Dr.Diff) because of the customer service and the fact that he always answers his phone and will help you out if you need it.
