Hi I need a little advise, I bought a set of Lakewood slapper bars for my 57 Chevy which has a GM 10 Bolt axle. When I installed the bars I removed the old shock plate that bolts to the u bolts. With the new bars bolted in I only have about 5/8 of an inch for a rubber snubber between the spring and traction bar. To me that doesn't seem right. Is that my springs are to flat with very little arch? I will post some pictures later.
