Drum brake swap from 7 1/4" to Jeep 8 1/4"

I've done many searches on this and I'm still not 100% sure. I have a 3.55 geared 8 1/4 rear out of, I believe, a 97 Jeep Cherokee. I'm intending to install it in my 73 Duster this winter. I am fairly certain that the 10" drums from my current BBP 7 1/4" axle should be a direct swap to the Jeep rear as it has tiny 9" drums. I'm hoping that someone on here can tell me so I know what I'm getting into before I tear into things.

Why not simply use the Grand Cherokee or Dodge Dakota disc brakes on the rear?
They bolt right on the 8.25.
About the only thing different is you will need longer wheel studs because the discs take up a bit more room than the drums.
I put them on the 8.25 in my Dart.
