I am converting my son's 69 from power drums to power disc and have run into a problem. Using the original booster there is not enough room left to install the master cylinder. What booster/master cylinder combination will work?

 

I think they came as a matched pair...

 

check with one of the aftermarket brake companies like Baer brakes or Stainless Steel brakes and I'm sure they could give you some ideas of what you need to get.

 

Thanks for the info , I got it to work.
