Just a heads up I bought those same sliders at first and the bushings for the rear spring eye were like socks on a rooster. After some debate I bought the caltracs and they were a much better quality part, fit perfectly and an all around beefier part. I'm sure you can make them work but I wanted to let you know the set I got were off by a mile. I think the speedway sets are the same as the amazon, both look the same and are gold anodized.
