I used a new 95/96 booster and master from O'Reilly's, the 1/4" spacer was made out of aluminum. I should have the spacer drawing still, I'll post up some pics of it later if i can.
I then replaced my factory proportioning valve with the Wilwood adjustable proportioning valve/distribution block. The bracket, screws, and pre-bent line setup that Wildwood sells for the prop valve is near perfect. The pre-bent lines are of no use as they are both bent wrong for the application and equipped with the wrong flare nut on the master side. The other issue is the outlet for the rear on the prop valve is very very close to the inner fender. A hand bent line will work if you bend close to the flare nut. I'll try to post up some pics of this too.
I used short lengths of pre-bubble flared 3/16 line to make the master connections and double flared the other end for the proportioning valve. The master flare nuts are 12mm and 10mm bubble flare and the prop valve side are all 3/8".
The swap was made easier by the prop valve as I used the included brake light switch instead of grinding the booster rod to make the lights work.
I might have missed something but I'll try to get some pictures up later today.
