@Pete Mcan you move it to the right section. Also welcome to cc. make sure to put it in the registry

[89 MJ]

 She looks like a great truck to build! What are your plans for it?

[Jesse J]

she is a beautiful truck. 

[Misfit_MJ]

Thanks for moving to the correct place! 

[Pete M]

no problemo.  

 

by the way, you want a 242.

Change of plans on the build for Axles, found a killer deal on a 31spline 8.8(with 3.55s and Disc Brakes) setup for an XJ with matching HPD30 locally. Deal comes with front and rear drive shafts from the XJ.  Now just need to figure out wheel spacers, gearing and locker for rear axle for now.      

[Pete M]

more gearing is better   

[Misfit_MJ]

Pete, what gearing do you like for street duties with trail riding on weekends on 33's? I'm thinking 4.56? 

[Pete M]

4.56 is what I would suggest as a rule of thumb for more street than trail, 4.88 if more trail than street.  it's a bit up to personal opinion though. 

[Misfit_MJ]

Radio install was painless. How are you guys getting RCA cables and amp turn on wire to the head unit? Area behind radio is sealed pretty tight.

Do you know a good Magician?

There's space at the back straight down.

Audio system completed, now to move on to the cooling issues.  Flushed cooling system and added louvers to the hood. Need to get it out on the highway to see if that fixed the issue.  

[Jesse J]

dig the louvres!

[Misfit_MJ]

thnx!

4wd conversion question? In my area (DFW TEXAS), I'm not seeing many XJs  with AX15s. Do see plenty of 4wd XJs with autos... Should I buy an XJ with and auto to swap over, of still try to locate a ax15 from an XJ or TJ.

auto or manual is entirely a personal decision.  it may take some time to locate an AX-15, but I'm sure you will eventually.   there are some threads on man-auto transmission swapping in here:

Been busy, but picked up an 8.25 (27 spline) rear axle(Ford 8.8 didnt pan out) . In the process of converting it to 29 splines (not going over 33s) with ebay shafts and an open carrier from a 97 XJ. Also picked up 4.10 gears and  a Spartan locker  for  a crazy low price. Nothing fun to show yet, just cutting off shock brackets and leaf spring perches. Hopefully soon can start working on the hidden winch front bumper and get the 8.25 swapped in. 

[Misfit_MJ]

Found an Ax15 from an XJ with a NP232J, will this setup work for an easy bolt up conversion?

[Pete M]

as easy as it can get.

You probably have already got the rca cables run, but here’s what I found works. The area behind the radio is pretty limited on space, but as fiatslug87 said it’s very much  doable. I used an electricians fish tape to pull all my wires through, but a coat hanger will work just fine. Tape the wire to the end of the coat hanger and feed the other end down and out of the dash. Then all you have to do is pull it all out
