so you want to put a dana 44 35 spline arb in an isuzu dana 44 with custom 35 spline shafts?
iirc that rear uses thick gears (like a rubicon) so you would need to order the correct arb. please check with someone like chase at ecgs or randy's before ordering.
i've also heard that the shafts in those rears are 1.5" out by the flange and then neck down to 30 spline 1.31 size at the carrier. is that true?
edit: i don't know any reason why it won't work as long as the shafts are 1.5" by the flange and it's compatable with the thick gears.
I'm not sure, I can get the number of the ARB I have tomorrow to let you know. I have spoke to Chase before, but at that time I have not considered using a rodeo D44. I would also need to cut down one of my shafts.
