It is getting to be a problem now with all of the older Fords. I have a 2wd Sapphire Cosworth 1990 and it is the same ,some parts now are just not available.A while back I went to the biggest Ford spares place in Hampshire to pick up some parts for a guy in the US as he could'nt get them over there. While I was there I asked the guy if they may still have any original parts for my 2wd Saff. He thought this was highly amusing and shouted across to some other guys " hey he wants to know if we have any parts for his Sapphire Cosworth", lots of laughter. He then turned his big computer monitor around and showed me what it said, "Zero parts available suggest try owners clubs".
