death shake options

My rear drivers side sf center mount went out with rust. The hole was completely punched out with rust, so using a standard replacement mount was out. Got some giant 2.85- 3 in washers and then a polyurethane roll at McMaster Carr and cut off about 1.5in thick pieces to use as bushings above and below the frame. I tried a hockey puck (official puck from czech republic btw 
) but it was way too hard and got vibration noise. The polyurethane works good right now as long as it holds up against the elements next winter. I did both sides rear center, and was able to replace the rear backs with normal mounts. Lucky the nut held its place on the back rear. I really didn't feel like cutting a hole through the wheel well to get to it. Rust throws in a whole new challenge on repairing these old boats. Took it on the highway and ran it up to 85mph with no shimmy. Replace all the sf mounts if you get the death shake.
