Historic rallying in the US has no strick regulations. You inter your car in your National Class and then if it is an old car you put an H after yours number plate and you are in the Historic class. There are no Historic Stage Rallies. I can try to change this as I have ogranized some rally sprints and rally crosses. Even if I just start off with a few cars. I can get 6 -8 cars from just my friends. So fender flares are not a problem but I would still like to use the right ones. Do you have any photos and specs on the suspension. Like spring rate, travel, Strut shaft size. Ken
