Go to Stable Energies in Garfield NJ, they are a racing shop and they have them in the show room, though you may want to call first. Or try another speed shop near you.
Good Luck, as many of the seats are made for teeny tiny bottoms of below average size, american average that is. Their are seats in all sizes but you have to check available space in the car as well. Most fixed back buckets fit easily but the recliners can be an issue.
