Well:
Try to locate a second hand one.Even with a damaged distibutor, you're still with a struck deal with that rover.I wish I can help you out, as I have a second hand parts supplier here in Florida, but don't know if they might be able to ship to UK.Anyways call them and find out.Their website is
www.roversland.com I have posted it a couple times...
I wish they could give me a discount or so for bringing more LR owners to their business.Will think about it too.
