Is your current seat cloth or leather?
Does it have heated seat and or lumbar adjustment controls?
You can go here Car-Part.com--Used Auto Parts Market
and enter your info, select Park Ave 1980 and up, then select Front Seat, and finally the option that fits the seat you have.
Then you can see which salvage yards near you may have one for sale.
I see a few listed in my area, from 75.00 up to 150.00 .
