Fixing door Locks. Possible to switch to power?

[AZT]

Ok I bought my 91 Eclipse and the door locks wernt working, I looked at the mechanics themselves and the conections on one door were broken and then other doors lock just wouldnt work. I have it so it locks now, but I hate having to open from the passenger door to crawl across and unlock the drivers door. What I need is some locks off the doors and the key that fits them. If anyone has some on a parts car Id like them. I know that im kind of in the wrong forum on this but I cant post in classifieds yet and I want to fix this. Also, I have heard of changing manual locks to power locks. How hard is it to do that?
