Any body ever done a rear sub frame rebuild/swap on a BH?

My car had an unfortunate encounter with a hill over the winter an one of the wheels is towed way in, think I bent what ever piece controls that. Anyway, my plan was to rip another sub frame out of a junkyard, rebuild it, and then swap it into the car all at once. Figure this is the best way to limit the time the car is on jack stands.
I was wondering if anyone has done anything like this and had some advice on things like what brand bushings to get (I plan to replace literally all of them), and, well, any other advice you can think of.

thanks .... to whoever reads this, I guess.
