polyurethane front suspension cones

[rocketron]

Some years ago, these were available from Spectra Dynamics in North Wales ( they're now called Flo-Flex and a very helpful), but did not sell enough to merit production. The last ones were binned!
Were they any good and does anyone have some to sell. A good friend is restoring a Mk1 Cooper S, and would like some.
Ta! Ron.
