2nd Gen Non-Engine/Transmission will 02 D70 disc brakes work on an older D80

[BILLVO]

I have an 02 with a D70 rear diff with disc brakes and was wondering if the brake assemblies will work on an older drum brake style D80 axle. I have started to sled pull and want a D80 ready to go in if my discs will work on it. I checked and the rumors of it being a hybrid of a D80 pumpkin and D70 tubes is not on mine its a true full D70.
