So Im trying to do my own impeller and ring installation on my 03 GTX. To make a long story short I screwed up installing the impeller the first time and somehow stripped the first few threads of the nut and impeller. Does anyone know if I can use rethreading tool to clean up the bolt and impeller and if so what size of tool? I looked at some rethreading kits online but they don't look like they come with a big enough tool for the large center bolt. Any suggestions would be greatly appreciated! Im really hoping I don't have to buy another new impeller.
