Yippee! Managed to free off one of the less manky ones today - one more to go and two nearly new ones to fit (thanks Dick in Cardiff, and Ebay!).
On the old ones, the metalwork and bolts are usable, but the rubber treads are shot. It's obvious you need the folding-over bit of rubber, as it keeps the weather out when the step is folded up. Without it, water will run down between tread and metal, and corrosion will be fast.
So, does anyone know if they are separate parts, and, if so what the number might be?
TIA.
Regards,
Simonm.
(getting it tidied up slowly...)
