LBP 10 x 1 3/4 brake drum availability?

Well, to make things easier and to actually get to use the new pair of drums I spent $70 on, I ran to my friends wrecking yard today and pulled a rear brake setup off a 4 door '71 Satellite that had an 8 1/4 rear. The parts were free, it's just the 200 mile round trip that kinda sucks! Haha
