Moser 60

Prior to stuffing a 600+ hp gen 3 hemi in my drag car Duster I’m going to first change the 8 3/4 diff. The 8 3/4 is living on borrowed time as it is with 1.45 second 60’ times even with the crappy 410 LA motor. I’d like to use a D60 instead of a 9” since the price for one ready to roll is about the same. And of course I’d rather stick to mopar tradition than sell out to the 9” crowd. Has anyone had experience with a Moser D60? What do they weigh compared to the 8 3/4?
