Well i tried to get the ac system evacuated today, but nobody is open on a Saturday. And since I work 4am to 6pm, I miss everyone' hours during the week. Hopefully I can get it in on Friday. So today I just did some tinkering. Took the headlight buckets and the group 34 battery from my 96 xj. Ordered a new brake proportioning valve so i can swap in a WJ booster and get rid of the load sensing valve. Just wairing on parts now. Was -10 this morning, but the sun was intense. Chrome headlight buckets from the 96. " />Measured out the perch widths on the 8.8 i need to build up. 5.5" in to center from the cast ebrake spindle. Kind of worried about the deistance of the perch from the caliper.
Started on the brake system overhaul. First step was to delete the Height Sensing Valve. Important to note, i will be using an XJ brake proportioning valve, and removing the MJ valve.
I used this Coupler:
to joint the 3/8's lines at the T-fitting here:
This line comes from the lower front of the Distribution valve( do this setup if you are switching to an XJ valve, otherwise you will use a different rear brake hose and use a different feed line if you are keeping the MJ valve.)
Remove the load sensing valve from the frame, and unhook the 7/16s line from the sensing valve.
Install your extended rear line( i just used Rusty's XJ extended lines)
Once the last remaining parts come in tomorrow, i will finish the install noted for the distribution valve and the front brake lines.
I haven't played with an MJ, so take this advice for what it cost you.
Why don't you turn the brake hose around and attach it to the line running forward, deleting the short section of tubing and coupling? Would be easy enough to fab up a bracket to bolt to the frame rail to attach the hose end to. Could probably mod the existing bracket to work in the new position.

By doing it that way, i would lose a good 2 feet of length to the rear axle. Not good when you have lifted the jeep. Mjs are unique in that they have a load sensing valve that is essentially a proportioning valve. It takes the bed height and changes how much fluid the rear brakes get depending on how much weight is in the bed. This means that there are 2 lines running To the rear, not just 1 like a cherokee. By doing this, I simply created a XJ brake system. So essentially what you see is no different than your XJ. The only difference, is the rear hard line originally led to a 3 way TEE that fed the rear axle hose, and the load valve. In removing this tee, you couple the feed line together, and leave the return line open. The only other way to do this, is to swap in the rear hard feed line from an XJ. OR use a hose with a 7/16s double flare fitting from the return line to the axle.

XJ Valve is in. It's a tight squeeze getting the rear lower fitting screwed in, especially if you have big hands. Bled everything with help from a buddy, and she stops way better! I actually feel safe slamming on the brakes now. I recommend screwing in the lower fitting first, then the rear fitting, then the top fittings, and use stubby wrenches.
Well that was a fun day changing the heater core. Took about 9 hours from yanking the seats, to getting the dash fully re installed. And I'm still not done. My carpet was completely soaked from snow and coolant, so I'm waiting on it to dry before I put it back in. Right now I'm working on eliminiting the POs super scetchy fog light and light bar wiring. Building all new relay harnesses from scratch. What a PIA.
Cool smoker in the background. Did you build it? I haven't seen one of that type, typically see the firebox on the side. Are there benefits to the the firebox being centered and below the cook chamber?
