Does anybody know anything about these nuts. Sat. before last we took the cars to a car show over in Indiana. The judge was getting ready to judge our 3 cars when I went up and asked him a question. We got to talking about the cars and he asked me if I was going to take the 69 Valiant to the Nationals this year. Told him I didn't know yet. He told me that the only thing the car needed to go there was the factory spring hose clamps. The corbin clamps and he said I needed a special nut that goes on the top of the shock bolts. I wasn't aware that there were special nuts that went on the top of the shock bolts. Said it was like a lock nut. Does anybody know what he was talking about and where I can get them. I would like to put them on just in case I did decide to go to the Nationals with this car.
