Need some brake help ASAP...

I am about to start a brake booster and master upgrade on my 91 MJ. I have a booster and master from a 96 XJ. I want to use the cherokee prop valve in order to eliminate the load sensing prop valve on the rear of my truck. Here is my problem/question: I just realized today when pulling the booster and stuff from the XJ, that it was an ABS model. I need to know if the ABS and non-ABS prop valves are the same??? I am worried that this ABS prop valve is not going to work for this swap...which sucks. I looked at a buddies 96 XJ today that is non-ABS and the only differnece I could see was that his had an orange tag on it and the one I got has a green tag...

thanks -Justin
