In the right place to pick up cheap MK11 cortina parts? I have not seen a sierra for years , never mind a Cortina. They have all rusted away years ago! ah well. I checked cortina gearbox mount on ebay, and immediately found one ( with photograph)from a Morgan specialist. Now you know.
By the way, the gearbox, and its 2 litre lotus engine are going into an Austin Healey Sprite ! Next problem will be back axle. hehehe
