For me it was the front inner wing brackets, left them in case they assisted in supporting any future inner wings, they need to go. That sorted on the subject of wheels, I have a bid at the moment on some 16 inch Aston Martin wire wheels, could be a steal at the price but need to find 80mm splined hubs to fit or adapt to the MX 5 hub. Thinking head on, but any advice would be welcome.
