Press the center bushing out,(you'll need a lot of push.)Go to the hardware store and purchase a couple hole punches one the size of the bushing and one the size of the whole in the hanger.
I used one eighth inch thick rubber,thicker would be better but that's what I had on hand.
Cut some donuts and press them on to the bushing,I started with a couple and inserted them into the hanger,then just keep stacking them up.I used Parker O ring lubricant to help slide the whole thing together.
Make sure the donuts protrude beyond the ends of the bushings so when you assemble them the large washers at each end will squash the whole thing together.Good luck PK.
