a1airboat Darrel I use a 4 lb plastic dead blow hammer. If you hit the rim it doesn't dent it. I of the cobra companys has a socket that goes on the spinner with a breaker bar to remove the wing nuts. DON'T FORGET TO SAFETY WIRE WHEN DONE.
Speedway sell a nut for these wheels too like the F1 cars, but you will have to drill the spindle and safety clip it on. Rick Lake
