An 89 mustang lx with manual windows, practical/possible to turn it into power windows??

 

Should be. I would think just about any aftermarket dealer would have power window kits. Try some of the vendors, latemodelrestoration.com, or google search it. Of course you could also probably buy used doors with power window/locks and go from there.

 

Can't really answer your question, but would offer the suggestion that you post this in a forum other than "Detailing". You might not get a little more traffic for your question that way.
