this has prolly been coverd a millon times but my 87 TII has a nasty camber problem in the rear. I was wondering if this is a wore out/broke DTSS, other suspention parts, or just poor alignment?

 

Camber is not adjustable when stock. The things to check would be the inner trailing arm links, the subframe link and all the bushings.

The rear end gains a lot of camber when lowered, even if it's on stock springs, they've saged in the 20 years that the car's been sitting on them, making it lower.

 

You can get a couple of different rear camber adjusters that can fix the problem if the car has been lowered like Black91n/a said (and check the other areas he suggested anyway). Racing Beat and Mazdatrix as well as some other places have different versions you can get.
