I'm not sure if the seats are different, but I do know where you can order the seat covers, and other stuff online, check this out.
Part #20 should be your seat covers, they are $182.00.
You can look at the exploded diagram of the seat here, I'm not sure if that will help you with getting the gears fixed for Part #12 the ACTUATOR. Front Seat Adjuster - VERT(FRT VERT)(W/FRT VERT POTENTIOMETER)
if you have to buy that new you are going to pay almost 400.00
Hopefully somebody is better able to help you soon, wish I could have been more helpful.
