For all of my Spring mods, I as well used 'plastic' as a starting point when shimming the spring. Here are a few pictures giving you an idea of what I did to address the issues. The first spacers were made of ABS that I 'double walled', then something I cut out of an old cutting-board. Once I was sure of what I needed, I used some pipe I had to make a spacer with a broader base foot-print and had a machine shop turn it down to look more 'in scale' with my project. To protect against the dangerous "Coil Binding" I bought a couple of front end Urethane bushings from an auto parts store. Bored out the ID to match the shock rod OD then slit one side of the bushing as to allow me to open it enough to slip over the rod. I then wrapped a bit of wire around it to hold it in place. Clearly, none of this should be done by someone that is inclined to ride aggressively, not keeping in mind the potential limitations of their rear shock. I figure I am safe for one very hard landing, then I would likely need to inspect and or rewire the bushing. For me, that's ok because I am a slow trail rider and stay well within the 'limits' of my very comfortable suspension. Good luck, stay safe and Happy Holiday. Gerry
