james, an fyi, have been searching for new seats for my cav gt. have found the sparco rev plus seat will fit width wise, apprx 18.5". then we will cut down the top of the seat, just above the belt pass throughs to make the seat low enough to fit, approx 32"
reason for all this is i'm 5'5" , the original 40 seats just dont work for my size and i like to sit more upright
