Pushrod issues with either one?
When I did the WJ on my 89 I had to open the hole up a little bit and grind a flat spot for the brake light switch.
Lots of videos on the swap.

WJ versus 95 to 96 XJ booster
Actually, the WJ booster is in some ways easier than the 95 to 96 XJ. I've done both.
Does one work better than the other?
Also, what do I with all the wiring left from the old system? There are plugs everywhere! And my battery went dead. Any relation to unplugging all the old brake stuff?
I don't think there's any difference between them but I don't know about ABS for certain. They are not different for non-ABS. The flared fittings on the new MC are different and will have to be changed.Should I use the 91 or 96 prop valve?

The newer ones will have am electric motor back up.
Its been my experience that while the back up does indeed work it doesnt work that well.
Bracking performance is about the same if you stall and have no vacuum going to a vacuum booster
Spidermikey88, what mods did you have to do?
What did you do about the prop valve?I did the wj booster and master cylinder upgrade on my 87 and it made a huge difference. But like the other guys have said, you have to do a few modifications to make it work. I think it was worth it though and I'm about to do the same thing to another xj I just picked up.

I kept the original prop valve and then took the brake lines from the WJ master cylinder and had the fittings replaced on the prop valve side. I still have drum breaks in the rear so I didn't want to use the WJ's valve. I can take some pics tonight if you want to see any it.What did you do about the prop valve?

That would be awesome I need to figure out what to do on my MJ.I kept the original prop valve and then took the brake lines from the WJ master cylinder and had the fittings replaced on the prop valve side.

First I had to bend the pinch seam at the firewall up a little so it could fit the larger boosterThat would be awesome I need to figure out what to do on my MJ.
