I also didn’t like the wobble from the spur gear so I modified that too. I was thinking about buying a Strobe Sprong on eBay but then I read some one else used a bonnet to make one. If you don't know what a bonnet is go to any hardware store (Lowes, Ace Hardware, Home Depot) and go to the pluming section and ask for a bonnet. They are made for faucets. I bought the biggest I could find. Cost me $0.68. When you install it you remove the spring that comes with the kit. Place the slipper stuff on the transmission input shaft. Then place 3 washers onto the shaft. Place the bonnet over the washers. This keeps the bonnet centered on the input shaft at all times. I then used an old Emaxx slipper plate flipped over to keep the bonnet in place. A lager washer would be fine. Then use the same nylon nut to tighten it all up. There is still a little wobble but not much if any. When using a single nut to keep it tight I don't think you can ever keep the entire wobble out.
