I am going to put a heavier set of springs in my SC10 II and wondered if there was a chart in existence somewhere to get some part #'s from.I looked at a couple of online microfiche sites but the only #'s listed were for the standard ones even in the pages for the X sleds which would have the heavy springs.I noticed a set of 3 green paint marks on one of the springs from my skid and wondered if Doo used this method to mark the springs the same way clutch springs are designated.Anyone have any info?
