My rx-7's sunroof was broken into. It now leaks. Can i replace the just the parts in it or should I just replace the whole assembly?

I've heard about glass, fiberglass or sheetmetal replacements. Should I do that?

 

Depends on how much damage was done to your sunroof and if the assembly was damaged as well.
Pics would help...
idk about the replacements, but may be something to consider
