1996 Geo Tracker Load Sensing Proportioning Valve Leaking

[ddbernier]

I have a 1996 Geo Tracker, 4x4, the Rear Load Sensing Proportioning Valve (LSPV) is leaking and I cannot find a replacement. I need to replace the brake lines, the rear cylinders, drums, and shoes as well as the front calipers, pads, and rotors. Is there a good swap for a LSPV or a manual version I can use? There seem to be some modifications out there, but I don't want to cause a braking issue with the wrong replacement.
