Mate, you can get them cheap as chips on ebay for a new pair. Most of them will fir just fine. I changed mine ages ago with some fine mist ones for about £4 and they are great!
I wouldn't have thought so to be honest. I would have thought that the cut-outs on the bonnet would be different. Plus they look alot taller than the standard.
Haven't you got a scrap yard near you? A Rover 600 may fit.
