I have the chance to buy a rebuilt rear end (whole assembly from drum to drum) for 300, the gears are 3.73. I was reading that 4.10 are the best for the AOD so I was wondering if I should wait til there is a 4.10 rear end for sale or pay the 500-600 for rebuild and parts for the one I have or go with the 3.73 that is rebuilt. Is the extra 200-300 I will spend worth it. I want to add a supercharger down the way and saw that 3.73 my be better for the supercharger. Thanks for the input.
3.73's or wait for 4.10's

3.73's will be fine with your auto, in fact i think thats what ford suggests. ryan has them in his vert, along with some other people, they might chime in if they see this. i have 3.73s in both my cars and love them, granted they are both manuals.

It was a notable difference when I jumped to 3:73's in my hatch, from the stock 2:73's. Still plenty driveable, and yes first gear is pretty much useless now, but I still try to use it so I don't lug the motor. (some wierd power loss right now)
I will be going down to 3.27s as every mustang I've driven with the two different ratios, i prefer the longer gears and better freeway driving with the taller gear. To each their own. With a 331 and a S-trim, mine will have plenty of go with the combo.
It all depends on the driving. And how YOU really want your mustang to feel.

yep it should be fine for you. Also depending on your driving style/Plans is the differential in that rear end

If cost was the same I'd go with 4.10s.
But in your case, future Supercharger and I'm guessing your t-lok is smoked, don't pass on the good deal.
