Ed you asked me a few weeks back the height of my running board. I finally got my car back on the ground and I measured them and they are 7.5" at the rear fenders and 6.5"at the front fenders. Are you mounting your master cylinder on the firewall or under the floor? I'm using a standard GM disk/drum on my 32 and mounting it on the firewall.
When I started the rear was about 14"..I think I'm down to about 9" without lowering blocks..plan on installing 2" lowering blocks..so we should be close. I had a set of Mustang II front springs that already had 1.5 coils cut off..waiting for them to settle.
Using the stock 95 Camaro brake pedal so I needed to lower the double diaphragm booster, attached some pics.
Waiting for an offset clevis before final mounting....btw I have a 3/16" steel plate mounted on the firewall inside that mounts the power booster.
