i have a set of axles that i got indirectly from jeff's 73 blazer and i was thinking of putting them in the jeep. they have 373's right now but i would put in 410 bc i have a set of d44 gears and a detroit that could go in the front (assuming the gears and locker from my cj d44 will work) and will find a set of 410 for the rear and i think that it has posi in it but i'm not sure, i might just weld it. so what is the consensus. i have 37's to put on and am extending the wheel base of the 5 by 6-8 inches and i have 4 to 1 in the tcase already
