I went out and remeasured and got ~5.25" for my 44 and ~5.5" for my 8.8 Maybe the TJ one measures a bit lower since I imagine it's rotated up more than an MJ would? Dunno. :dunno:
If I was sticking with 4.10s, then the 8.8 is hard for me to pass up. I can get one for $125 (complete and with good disk brakes) but 300 is a more common cost across the country, $100 or whatever it is for spacers, and $300 for a luchbox locker (or get the factory posi). Total cost for me would be under $250 (if I went factory posi), but figuring the axle costs more and the locker is desired, that totals $700.
But since you're dead set against the 8.8, then my vote is still for building a Dana 44.
