I bought a new rear shock online that was a take off from a Trek Fuel. The eye-eye and stroke length matched what I have on my MTB, which is not a Trek Fuel. I figured I could just use the bushings and mounting bolts from my old shock (a 5th element coil shock) but I'm stuck...The hollow cylinders for receiving the mounting bolts at the top and bottom of the shock aren't quite right. The top cylinder is a few mm short in length and a little small in diameter, so if I use the bushings from my old shock they overhang past the mounting cylinder and wobble around a bit. On the bottom mounting cylinder, the hole is too small to accept the mounting bolt from my old shock but the length is correct.
Can these cylinders be removed? I was thinking that I could just swap the cylinder and bushings from my old shock to the new one, but the cylinders seem to be rigidly attached.
