What to do about convertible top?

[physicusstang]

I have just bought a 87 Mustang LX 4 cyl. Convertible for a great price ($100). It needed very little engine work at all, but the rear window on the top has come out of the seam at the lower portion. Can I replace the rear window section or do I need a new top. The top is in good condition, no leaks or anything. I also wanted to know if I can do this myself.

I also had a question about my power windows and mirrors. The only direction the mirrors move is to the left, all other controls for the mirrors don't work. The window on the drivers side and the rear small window dips out of alignment when lowered. How can I fix this?

Finally, the doors need adjusting, but I don't know how to do this. The passenger door needs to be lifted in order to shut and the drivers door doesn't stay closed at all; you have to push it in to close it. My dad said that there was a little rust on the door hinges; might these need replacement? As always, any suggestions are welcome. Thanks.
