cpp sells a pedal assembly to move the booster to the firewall. I bought one for my 52, just waiting to receive it. I just bought the pedal assembly and went to the local auto yard and got a booster/master cylinder and combination valve for about $20-$25. Got a practically new booster off of a 2000 or so chevy 1500. Got the master cylinder and combination valve off of a 80's chevy pickup.
