During this bad weather, (winter), I just reworked the front shocks to have more rebound dampening and haven't had a chance to try them, but I'm sure they are as good as any other shock, way better than stock, and you can rebuild them. The rears were doing quite well, but the front had too little rebound dampening and I have just fixed that, I hope, but need to test it.
I'll have to take some photos of my fenders for you, but the plastic came from http://www.speedwaymotors.com/in the form of a 10’ or 25' X 22" X 1/8” rolls (http://www.speedwaymotors.com/Colored-Plastic-Rolls-25-Ft,31414.html ) and the frame work is a piece of 1" X 1/2" channel iron bent around the tire and supported by 2 1/2" square tubes and stabilized at the front.
photos later today, hopefully.
