The chap selling the wheel covers on E-bay has withdrawn them from sale as he now wants to keep his camper (good decision it would seem!). So I am on the hunt still for some wheel covers. They don't need to be new or concours, just some chrome wheel covers.
These covers are a "compression fit" ie they come off when you kerb the wheel. And the commer rims dont have the indentations to take them. Good idea though.
