I got mine from a junk yard, they are not hard to get off. Just be sure that it's the right one - there are a number of different sizes for rear 44s. I THINK (measure to be sure) that the waggy, like mine, has 11 X 2 brakes - this is the important measurement for drums, as well as bolt pattern. The backing plate also differs even if it is the same size - scout backing plates are different than waggy blah blah blah.
I ended up ordering parts from a place in Vancouver, BC, and got the wrong backing plate. He was good to send me the right one once I made him aware, but it took another 2 weeks to get it.
I know you were looking into disks, you might want to reconsider because even used drums are going to be 30 ~ 70$. If you need 2 of those, plus backing plates (about same cost), you are already talking 120 ~ 280$ - and that's for USED junk!
If I had to do it again, I would have gone disks, but at the time I couldn't get a straight answer on the parts that I needed. I still may go disks next winter.
Think about it. I've gotten used parts from Vancouver, BC, and some place in California. If you want their phone numbers, email me and I'll try to dig them up for you.
ps. If you go disks, I'll be interested in how it turns out - you can be my gineau pig.
