Parts and Tools, no idea

[Bmwtvboy]

First, where can I find the rear-subframe bushing tool to borrow or rent? Silly to buy one for one use. I did see some guy in Russia do it with a jack lift, heat gun, hammer and lots of work. Tool makes more sense.
Second, I don't want to buy used front/pass door actuator because it eventually will fail again. I found parts from China but not sure they're worth it. Seems to be only two alternatives, really expensive OEM or used. Fixing the motors is not for me. Any ideas on what alternative parts maybe I can't find? BTW, are the front driver/passenger actuators interchangeable? I don't see how?
Thanks, J
