I have been fortunate enough to come across Neil Adderidge, who I must say has the most knowledge of Ford Sierra and other historic parts going. For all parts Sierra/Granda/Escort vintage, and what will fit with what, and year. Phone him with your questions or parts you are looking for. Genuine, helpful guy, worth keeping a note of his number 07507683000. He's more than happy to help. I have told him that I would mention him on here?
He talked me out of a purchase, and helped me with the clutch pedal issue on my Hood +
