Windsors were a Rover dealer for decades, there were a couple on the Wirral. They still have parts in as they used to, they had the part I wanted there and then.
I could do with that number? I know of a bloke that may be the same one, you pay him 400 quid, you pick him up from the airport, and he fixes your car (in this case, 400 quid for HG), and then take him back!
When i last went to Mazda Wallasey, which i think is an afore mentioned Windors, they had Rover and MG badges up on the walls in the parts department, try there
Xpart in Wallasey is essentially the MG Rover Group official parts supplier. The distributor centre and specilist Autoservice centre are still located at Windsors.
Also try Rimmerbrothers online, they too specialise in MG Rover parts and can supply just about everything from trim to mechanical parts.
I've tried Rimmer Bros before. They were almost laughing as they gave a price on some stuff! Got the stuff from Mazda today, glad to see they still stocking Rover/MG stuff.
