Ted Mitchel's window lift assemblies work really nice with the added benefit of having the window rolling all the way flush with the frame and loosing the weight of all those old parts as Jack mentioned. My friend has it on his Pantera and it is a configuration used on late model Ford sedans, simple and works very well. The drawback to me was the cost ($700 at the time) so I went the cheap route with the Aerostar motor converstion. The new motor is direct drive, draws less amps with a lot more torque. I would recomend the Taurus motor conversion though in hindsight if you don't intend on ever going back as it is a lot simpler. Either way,make sure you put all the alignment shims where you found them or you will have fun lining up again.
Good luck with that.
