Peter... I am going to make my own from round polyurethane stock that I can turn down to any diameter or length on my lathe. My trail 45 will get a 1.5" or 2.0" body lift from these poly blocks. I need to research the best hardness for body mounts and will then make an order. If you are interested, I can order enough for three sets and make some up for you.
Anyone have experience with different hardness qualities of polyurethane to recommend a composition that would be best for use as a body mount???
