so... what Im looking for is rubber with an IRHD of something similar to a hockey puck. I need it 4 inches high and 6x6 on width. and I have no idea to buy something of this size. or even where to find it. if i could id just melt down a bunch of hockey pucks and use some wax paper and 2x4s and shape it. but I don't much trust myself melting hockey pucks down. What im trying to do is build blocks to sit between my springs and the body of my trooper. I put longer shocks on and when I ordered springs from old man emu I assumed they were longer as well. long story short under full flex my springs will just fall off. my plan is to turn the bottom of the block down to a diameter that will fit inside the spring and the top of the block to fit inside the hole where the springs rest against the body. while leaving 2" of space from the actually top of the spring to the body of my trooper. I live in ogden ut. If anyone knows where I can find a material like this or even order that would be awesome thanks.
