If I had the time and money and if my car wasn't my only mode of transportation, I'd try to do a 5 spd conversion for sure. But I think it'd be a very long processes and you'd probably hit ots of bumps along the way. If you depend on your Taurus working, I don't think you wanna start this project. If you have another car, may as well give it a try and be the first!
