Dumb question

I can't remember for the life of me where I stumbled into mine or if I already had them on the car when I bought it. But I did have a friend give me a set of lakewoods that were Chrome and they did not fit on the Duster as they didn't have long enough extensions to reach over the shock plate. I assume there for a Chevy or something? Also they weren't long enough as they did not reach the eyelet. If they don't reach all the way up to the eyelet and they hit back on the Spring they'll bend it..
chevy leafs longer from axle to the eyelet! mopar 19 inches and chevy 25 inches, most dirt tracks have a non moper leaf on a chevy rule!
