I have sold my Speedster, but have an extra pair of seats - that were purchased from Vintage Speedster, installed in my car by my son (as a surprise); but I never kept them in....because I preferred the standard seats that came with the car. So they were drilled for the tracks; BUT never kept in the car.
I tried to find them on the Vintage Speedster site; but it does not look like they sell them any more. The seats are vinyl, and I feel that they look good....but need to be broken in; and I was not willing to do that.
Open to offers; shipping will need to be paid by the buyer.
