can anyone tell me the thread size for the lower cam cover bolts?

 

Do you mean the cover that has the timing marks on it? I think they are M6, but Ford still sell the original bolts........

 

Thanks.
Yeh the small lower one, I've modified the cam cover to have a 3mm ally bracket to fit a crank sensor bracket for cossie managment but the sensor sits half on the trigger lug and half off it so I need some washers to space it out!! I've got the bolts!!
