I have a Tillett T8 1/4 pad XL seat for sale. Was mounted to a Tony Kart when I bought it, but does not fit me. Seems to be in pretty good shape, was never reresined or anything, but does still have some holes drilled into it. Call or text me, and I can send you some pictures.
Located in Huntington beach CA. But can also pick up at California Speedway some time.
