Northy, I bought a new driver's door last year. The original part number is 7751469959, which has no side impact bar - this is not available, but you can buy 7751469961 which has the bar. It does not come with hinges. I bought all my parts from Endon Services (http://www.allcarpartsfast.co.uk/ren...61-door-rh-cl/). Mike Aldridge is very helpful.
Rgds, Sean
