    I did the 4 wheel disc conversion, and tonite I'm plumbing everything up. I do have an adjustable prop valve for the rear, but my question is do i need to gut the disc/drum prop valve, cap the rear port and install the adj one per the directions? Or do I leave the stock prop valve intact cap the rear port and install the adj one per the directions???

    Per the directions on the adj one, it says to install between the MC and the rear brake line.

    I hope I'm clear in what I'm asking

    Thanks guys

    Take the original out.
    Adjust the valve to cut the pressure to the point that all 4 wheel will slde on a panic stop and then just a little bit more to be sure the rear doesn't lock ahead of the fronts.

    I didn't have a T fitting, so I gut the original prop valve, basically using it as a T or a dist block, blocked off the rear ports and plumbed the adj per the directions. Essentially the same thing you said.
    Thanks

    why not visit the junk yard and find a 4wheel disc car and snap the prop valve from it? there's plenty of lincolns and explorers around here that are 4 wheel disc that could easily made to fit

    But they're not adjustable. A prop valve has to be set up for your vehicle's weight, tire size, etc.

    a 94-98 mustang is (i believe) around 3600 and a fully dressed V8 Maverick is around 3400..... close enough to me. not to mention there's alot of parts that werent set up for our vehicles, but we make them work anyways :D

    I'm pretty sure the Mav's are a little lighter than that, especially with small bumper swap. but at any rate I think the adj. is a better choice overall.

    302-8 powered 1972 Maverick weighs 2786 lbs.
    1994 mustang 5.0/5speed 4416 lbs.
    1995 ford Probe 2.0/5speed 3319 lbs.

    looks like my info was a little off. and im not saying an adjustable wouldn't be better, i just wanted to let you know that it would be possible to do.
