You're not supposed to run space savers over something like 55mph, but that doesn't stop people doing about 90 on the motorway :roll:
There's a limited mileage on all of them that changes with manufacturer, some of the modern ones aren't meant to be used for more than 50-100 miles but again that doesn't stop people doing several RAC rally stages using them :roll:
Yours will be 15 years old though, don't know if that makes any difference :lol:
Try here, they've got proxy's and it looks like they're in stock. They come out to fot as well...
