Why do you want to narrow the axle so badly? Comanches are wide in the rear, so having a wider axle will let the rear tire fill out the wheel well some. It should also make the truck more stable.

What transfer case do you have in this? I see you’ve got a 700R4 like @The86manche has for his truck.

I wouldn’t be that worried about the pinion being off centered. The Ford 8.8 is the same way and I’ve got one of those in my truck.

I just looked up this thread: https://www.rme4x4.com/threads/700r4-transmission-2wd-to-4wd.32774/#:~:text=2wd versions work equally well,services of a transmission professional. It looks like you'll have to change the transmission output shaft. The transmission will need to come apart to do that.

Ok. I'm still worried that a 4x4 output shaft is supposed to be shorter than a 2wd output shaft. That is something to be sure of. I also have no clue if the 207 will bolt to the factory trans-transfer case adapter, which is why I recommended the NP241C, which would be hooked up to that transmission already. The spline counts might be different, engagement depths, bolt patters, etc. If you were to do an NP241C, you'll need to come up with some sort of shifter, as the shift pattern is the different from the Jeep ones. There are options for cable shifters out there.

That hour per day will make a big difference. Its funny how these southeastern trucks rust. I had one from FL and one from GA. Both needed floors and the FL truck needed rocker repair and bedside repair. My Eagle is also a southeastern car that needed and still needs some rust repair. I like the southwest much better for solid metal.

Cleaned up really well. I'm looking forward to this build and following along with this thread.

@70barracuda has the front bumper on his truck. An XJ kit would be cool.

They look really good cleaned up! Page 20 of my thread has a comparison for Renix TBs where it is easy to see before and after condition and shows the size difference.

Rock sliders hang below the body, so you’d see a large gap there. Rockers aren’t too bad to do on these trucks. And you can pull the doors off of any 4 door XJ. I’d recommend putting rockers and doors on it and foregoing rock sliders.

Your tail shaft may be too long, but if you’re lucky, you could get an adapter and NP241C that is driver side drop. That’s the route I would look into at least. You could get that adapter and transfer case out of an 88-98 GM truck with a floor shift transfer case.

I mostly agree with this. Advancing the timing with a high altitude CPS did have some improvement, but it only helps midrange power. I think the bored TB added a minute amount of power as well. Fuel injectors made no difference on my truck.

Will do. I emailed them last week with no response yet. I’m probably going to give them a call at some point.

Good to know!

I’ve read that having a TB spacer on these doesn’t add any power or mileage benefit anyways. I wouldn’t run it to be honest. That said, on this site, Mod 12 was a spacer on an HO XJ. He said it added a little bit of responsiveness and fuel economy. http://www.jeep4.0performance.4mg.com/diary.html

That would be cool!

Apparently Ares Fabrication is working on MJ rock sliders. I might consider getting a pair for my Comanche depending on what the pictures look like and if the quality seems decent. Does anyone have experience with this company? https://aresfabrication.com/shop/nostalgia-rock-sliders-m/

Have you verified everything is back in exactly how it came out? Fuel pressure should be verified at the fuel rail and all vacuum lines should be inspected for leaks.

I really like this Jeep and the way you're building it. Everything is purely functional and nothing is fancier than it needs to be.

This is fantastic! Drive safe and I wish you luck!

Anyone have these pieces between southern AZ and WI?

Found one that covers stock MJ wheels.

I think we do have one. I’ll find it in a little bit and tag you here

Good to know, thank you. Any swaps will get fuel injection.

I'm getting GMC Syclone vibes from this. I like it
