car seat

I have the power driver side bracket I took out of my car. I swapped it with a manual seat bracket. Less weight and I rarely move the seat anyway. Shipping would be the killer as it weighs a ton with the electric motor. You might look for a manual seat bracket like I did. Then you can get a passenger side bracket that is easier and cheaper to find.
 
The power tracks break and as a result, they go for a ton of money.

The manual conversion Paul mentioned works. If you're over 6' tall, it wont however IMHO. I'm 6' and had to use an extender because my knees were too close to the knee bolster (I felt like a clown in one of those little circus cars).

If you do the manual track, you can tap an extra set of holes (one set is already there) to move the seat back an inch or so.

Good luck.
