I searched around and found that new steel wings are £400 each. Ouch!! It's a great driving car but not in the best of cosmetic shape and not really worth spending that kind of money on it.
A bit more searching found a pair of fibreglass wings with a difference at less for the pair than one new steel one, so I ordered them and they arrived today.
VeeBee Wing is where they came from and they look a quality bit of kit. I'll report on how easily they go on when I do it, but the fitting instructions look comprehensive and easy to follow.
If you like them and decide you want some, please mention me when ordering, thanks.
