Jim Robinson, a V8 God...
I contacted Jim when he answered my wanted ad on Ebay for a water pump. He's based in Brougshane, Northern Ireland and can get hard to find parts delivered (particularly rare / early Rover P6 bits) quicker than anyone else I've ever met. I mean almost always within a couple of days, when others turn around and say "no chance mate, haven't seen one of those in years".
Visit Jim's site at www.jrv8.co.uk or call (028) 25861500
He's the most friendly and useful supplier of V8 stuff I've spoken to yet...
