Dropped the bolts off at the garage. They appear to be the same ones, the markings on the bolt head are the same too. They were working on my 260 when I got there. He was having trouble with some of the seized parts including the hand break cable.

For info the Ford part numbers are:
FMU 1456980 = bolt
FMU 1456979 = cam washer

4 of each cost me little over £50. You can probably find them cheaper elsewhere but I got them from the Ford dealer direct.
