I got them from the local "pick-n-pull" from a 83 Chevy 4x4. I grabbed the brake lines and proportioning valve along with the pedal rod. I went on a 50% off sale and paid $30 for everything.

It bolted up to the 2 factory M/C holes with out any additional brackets. I drilled out the firewall for the bottom 2 holes on the newer M/C. You can see the top 2 holes were not used (has a total of 6 mounting holes).

I used my original pedal rod and cut/welded it to the new rod which kept the adjustability by retaining the original threaded part.

It took about 4 hours to install it and then a couple more reworking the brake lines.

BIG difference compared to the original single pot M/C... It will put you into the dash if your not wearing the seat belt when you slam on the brakes... Takes some get'n used too...
