Dave,

Thanks for the tip with the pressure gauge. Sometimes the simplest things are overlooked. We found the prop valve to be the culprit. Went ahead and changed the MC anyway in favor of a alum vete MC for aesthetic reasons. Now with the new Wilwood valve adjusted so the rears lock up just after the front skinny's, it'll throw you through the windshield in a panic stop. My son is very impressed.

Jerry,

I actually found the fitting at Autozone. I was shocked. But the I opted to convert the rear line to 3/16" instead since it's disc all around and we're running the small D154's on all four corners. Seems to make it a little more responsive (we don't have to have the adj prop valve cranked in as much).

Funny how someone else's engineering can mess you up. Previous owner had installed an 8" single diaphram booster, 1 1/8" MC disc/drum, combi valve for disc/drum (PA-4). We changed over to 9" dual diaphram, 1" MC disc/disc, and the adjustable Wilwood prop valve. Works great. Now prior to turning it over to my son, I decide to do a safety check. Had him bouncing on the back of the car.....found the frame was hitting the rear drivers side caliper. Not good. Today he is cutting off the caliper mounts. Previous owner had them clocked at 12 o clock. We're going to clock them at 3 o clock. It'll give him 2.5-3"s of compression travel.
