This is what an 08 Dyna engine mount looks like after 14000k's, not real Healthy.
The new engine mount made such a difference to my Dyna, I coulda sworn, I was riding a Eglide or a Road king!
I put two spacers between the new mount and the frame, roughly six mm thick at each bolt.
Thats how much the rubber mount would have been pulled out of shape if you didn't shim it.
