Rear shock absorber bushes.

[Brian Murrish]

Does anyone have any experience of using poly-bushes on the shock absorber fixing to the rear axle. My rubber ones, purchased only a few years ago from one of our cherished suppliers, have failed already. The first ones when I rebuilt the car lasted over twenty years. I have had experience of putting polybushes on a Morris Minor and they have lasted indefinitely so I wonder whether a set on the Seven may last equally as long and if so where do I get them from? Members suggestions would be welcome.
