fastho the chassis is not the same i think he wants to be authentic and build a copy of the car they ran at 2000 world in japan.
the chassis looks simalar but it has differences that if you had a yoke you would notice. the batt sit further out from the center linwe and the t-plate is different as well there is a slit in the chassis which the yoke doesnt have for the strapping tape goes through.
and by the way barry all you have to do is drop the ss from the part # and that will be the # for the none ssg components you want.
twelth scale for life !
