Big database search of junkyards across the US.

There is also eBay and I found several sites selling used ones by just typing '1995 civic sunroof motor' in the search bar of Google.

Also the option of hitting the local you-pull-it junkyard and hoping the have and EX coupe or SI hatch to scavenge parts from.

Good luck!
