Disk brake conversion questions

[adamk]

I'm in the process of swapping 3/4 axles under my XJ and have gotten to where I am working on the brakes. I have the rear already converted to Chevy disks and I'm going to be running a Dodge 2500 master cylinder. Where I'm stuck now is what proportioning valve to use? For those who have done a disk brake swap on a jeep, what prop valve did you use?

I used a universal adjustable p-valve on mine. Similar to this:

Common 3/8 fittings going to it and pressure switch to activate brake lights.
In reality, you can also use a WJ p-valve or from any vehicle with discs front and rear and have same effect. The adjustability is nice but not required.

Perfect. Thanks. I'm going to be swapping to a WJ brake booster as well so I'll just grab a prop valve at the same time.
