Great product

It bolted right up. The only thing that was kinda pain was the adapter i needed for the rear brakes to the valve. But a few trips to orileys and i got it figured out.

Two things I wish I had known

The rear port is NOT 9/16-18 thread pitch. It is 7/16-24 so you will need a new fitting and a brake line flaring tool. Second thing- almost certainly your original low pressure sensor is a two prong connector. Pull the cap and check. If so, you will need item 52 which is made by the same company. It's $3.99 and you can just splice it into your existing 2 wire and it will work just fine. My thanks to George Perez for all of the free advice.

wrong part

This is simply a G.M. combination valve being passed off as a Jeep part. It is similar to a jeep part but the biggest difference is the 9/16 -18 rear brake line fitting won't fit the 7/16-24 fitting on the brake lines on the jeep (1980 CJ) A bushing would be an easy fix if one that size existed.So don't buy this unless youre planning to change the rear brake lines too and I'm still not sure if that's possible. Morris was no help at all solving this problem.
