Need rubber bushing for shock mount

[bmklawt]

Was under the trailer recently and noticed one of the shocks had come loose off the torsion arm, well actually all of them had.
I had original cut the bushings in half to install the shock, as seen here: Airstream Shock replacement guide
I can not find just the bushing, new or used locally, does anyone have an old shock they could send me the rubber bushing out of. I only need one.

I will installed the shocks with self locking nuts to prevent this in the future.

Your help is greatly appreciated,

Try any production garage, Midas, Meineke, that changes out little old ladies shocks when the don't need them and ask to look through the junk bin. Most likely you will find good bushing there.
