I bought a set from Eaton for my 51 victoria and they made the front set higher than stock. I replaced them with Aerostar springs from Napa, now it sets a little lower than stock but looks real nice. both sets rode good. if I had it to do over again I would just leave the original springs and call it good.
I am tired of changing springs, three new sets and the Aerostar look best and were the cheapest. the Eaton springs did not have the flat area on the top like the o.e. the aerostar does have the flat side and are good quality, they are availble from napa, autozone o'reilys ect. I can,t recommend the Eaton's.
