I think they might be setting level because they are made in mexico, and not near the spring we ran back in the day. they were made in America then. I have a set of 002-003 springs I`m not going to use, and the right (002) spring is weak, right in front of the rear spring eye. by the way, they are for sale, w/ the appropriate new imperial shocks. cheaper because of the weak spring, if any body is interested.
