Yes, i tried search. Couldnt find a definitive answer.

I want to completely remove the stock proportioning valve, install a adjustable one in the rear brake line, and install a line lock off the Master cylinder before it T's to go to the front brakes. I am willing to retube everything needed.

If you say i cannot delete the PV, please say why. Ive built two cars now with adjustable PV's (1923 T bucket and a factory five cobra) with no type of valve such as the factory PV, with no issues whatsoever (actually had to move the one on the T to the front lines, would lock up front tires cause they was so skinny!).

For those with line locks and factory PV still in place, how did you install it (the front brakes split inside the PV, no single line to install it).

Thanks in advance for any helpful answers!

FWIW, i will be doing SN95 conversion at this time also. Will have SN95 master cylinder, 94/95 spindles etc, ranger (fox lenght) axles and homeade bracket (like NRC bracket).
