I should be within 75 lbs with a scatter shield. I would recommend running the 1350 spicer tranny yoke, and replace your rear end yoke for the 1350 joint as well. USE A STEEL DRIVESHAFT. Have your shop fill your steel driveshaft with foam, and balance it on the car if they have the ability. That way you are balancing the rear end differential, axles, lrims, nuts and lugs, tires, everything. This will be something you can FEEL everytime you race.

You might be able to get a rebuilt Viper tranny. A new one will be about 3900.00. A rebuilt unit will be fine on a mustang, but they have to use the right input shaft, or you will need to spend time modifying your flywheel and run a dodge clutch and pressure plate.
