I use the same set on a elderly gk4 and a gk5. They do ride lower to the ground as they have an altogether "taller" profile than the rollers. Swivel is limited by the pin through the top of the tower, make sure your swivel brackets and pins are in good condition. Also there "should" be a 1/2" spacer at the bottom of the mount shaft
