8.25" rear axle and disc brakes???

My question is: Is it possible? and Does anyone make a kit for this mod?

It's for my '75 Dart. I currently am finishing up my tuning on the motor so that I can cruise with the car while I save up to rebuild the rear axle.

My plan is to scrap the 2.45 gears and go with aftermarket axles, a Powertax unit and 3.55 gears. If I tear it out to rebuild it, I'd really like to go to rear disc if possible.

Of course this is a big bolt pattern (BBP) car.
