Dorman / Motormite part number for late model arms is 42586. Should be able to source locally thru O'Reilly or other parts stores.
I have them installed on both my XJ and MJ.
Lifetime warranty to boot.
Yes, had no room in the back. It's worth it. Like anything the initial investment is the most cost. I lucked out, and my friend's dad stopped drinking (who does that? ) to lose weight for a promotion , and I got mine for less then half price. That included a mostly full CO2 tank. Get one with at least 2 taps, whether you run a single 1/2 bbl or 2 1/6bbl.
I have WJ belts in my MJ. There were in a pears vehicle I had on my property. Need to use both cab and floor to mach. The mechanism is opposite, so for cab side use pass for driver and vice versa. Floor should work same either way.
A D60 will be stronger and less expensive to build than a d44. My plan, eventually, is 60 front, 14ff rear and 35s or 37s. Or, if I come into a bunch of money a 60/9 hybrid front axle. Get your truck reliable, and setup before you go crazy with it.
As far as the striker, I know that some weld a piece of thicker metal in that spot. I need to move/fix the stricker on my MJ and it was already welded. Thinking about lining it up better, and just tapping whats there instead of using the backing strap.
I just used a spare chinexican 3/8" extension, and used a grinding wheel to re ove enough material from 2 sides of the extension to fit. Hopefully I will have my 4 wd swap done soon and no more french pos trans. Although, I can't complain too much considering it has outlasted the Turdy5
