Yeah that's right I'm doing a rear brake swap and i have a few questions about it. I believe I have all the components I need. I have backing plates, calipers, prop valve, and I think they are called axle studs (they connect the backing plate to the axle) all from a donor 95' grand. I have new lug nut studs, fluids, gaskets, and will be getting new pads soon. Is there anything I'm missing parts wise?
More importantly will I need to modify the hard brake lines on my XJ so they will properly screw in and fit with the soft lines from the calipers or into the prop valve.
I'm doing my swap on Tuesday/Wednesday (my "weekend") and this is a DD so I want to make sure I have as few surprises as possible.
Thank you guys.

I just realized this is the first time I've started a thread in the modified section.

I'm some what disappointed CF. I've asked this question 3 times in the ask the question thread with no response. So I figured i would get a better result with an actual thread, two hours in and nothing? Somebody has to have info on this, even if you just point me in the direction of another thread (although I'm sure I've searched them all)

Yeah you've got it all.

Just going to need to bore out the backing plates a little bit more.

I welded nuts to my axle tube and bolted my soft line to it, and then i ran new hard brake lines from the tee on top of the axle to the soft lines.

It's going on a D35 so I shouldn't have to bore out the backing plates, not until I go bigger at least or that's been my understanding. I'm glad there is nothing I need to do with the brake lines I was nervous about that, I don't have the tools or anymore cash to put into this project.

When you get to the brake lines, it will make perfect sense and will be easy.

You're good to go. Did you get the whole prop valve from the GC? Wanna save yourself a ton of work? Just swap the "guts" of the prop valve to yours.

You DON"T have to bore the hole bigger for a Dana 35.

You can used just the guts to make it a easier swap.

Don't know if you plan on modifying the xj e-brake cables or buying new ones. I tried to modify my xj ones when I did the swap. They didn't come out how I would of liked them so I went and got cables from napa and they just snapped right in. I think they were $40 for both. Driver side cable was a little long so I had to loop it.

I don't see how swapping the guts is gonna be easier? Seems like it would be more work however i didn't actually read how to do it because the write-you saw said he did not suggest doing it.

Then you pretty much have everything you should need.

Huh? One cap, removing the guts and putting new guts is harder than swapping a complete prop valve?

Ok, like I said I didn't actually read past, I do not suggest this method, and just assumed it would be difficult. But that sounds pretty easy.
