Upgrading Master Cylinder

Call Mancini to make sure but here's the parts that you should need:

- Master Cylinder MRE3460,$99.95

- Adapter plate with 4 holes to slide over firewall mounting studs MREAR6719 $39.95

- Adjustable brake pushrod MRE316 $42.95

If you have a manual brake push rod you can reuse it instead of buying the adjustable.

I'm using this master and adaptor plate with my stock manual push rod. Hopefully you installed the proportioning valve from the 73 Disc/Drum setup. Without a booster your pedal effort will be higher but not unbearable.
