I have a '95 conv. The drivers side was broke also. I found some 2001 seats, frames and all. but no harness, for the power seats.
I do know the fronts will fit. And the four prong connector on your original seats will fit the newer seats but you'll have cut and splice.
Our cars have one hot and one ground, while the newer seats have two hot and two ground. just cut and splice. You'll figure it out.
as for the back seat I don't know, my back seat was fine.
