noobish question

[internetautomart]

my head hurts so I'm not able to search straight enough

1. BC and BJ rear bar interchangeable?
2. 98 forester what can I use?
2b. 98 forester LSD in rear?

I've got a BJ rear bar in the garage (bought it for my wagon never installed) and now I've got the BC which I plan on keeping for a while.

My buddy got a 98 forester in the yard (that's why I asked for forester wheel pic, which is on the top of my screen again) and he can get whatever I want off of it fairly cheap. sadly someone bought 1 wheel off of it, so I'm not getting the wheels in the end. is there anything else to grab? rear arms for the sway bar swap are on my list right now. maybe the motor (unlikely)

Springs and struts, maybe. Bumper fog lights. Transmission, rear end? Buying a single wheel somewhere shouldn't be too bad - especially if it's the gold trim (barely noticeable when it's on the car), not the gray (a lot less common).

rear end is what I am thinking. I'm trying to find out about ratios though.
