Glad you got the clutch working ok Steve but 40mm sounds a vast amount, are the rubbers the same design as the ones that came off? If the old ones are ok I guess I would just fit them again, then possibly get hold of an old cam cover to modify during the winter. Were these real Ford mounts or pattern ones? It is part of the fun? of a kit car that you do one job and it creates two more, good luck.
