I'd stay away from those seats. I've had personally experience with seats from Ebay and they don't last. Spend the extra money on a good brand of seats like Recaro, Sparco, or any other major brand. It will last and hold up. Now as far fitting aftermarket seats all you need are seat bracket adapters for the brand seat and for your make and model. Most cost about 100 bucks per bracket.
