Help Please. What size (bore) are the 2 brake and the clutch master cylinders ? ( single pot calipers as early cars). Also, what size , part number, are the needle roller bearings, there are 7 in total ?
Thanks, Peter.
 
doesn't the parts book give you the bolt size? from there its only going to be a few different nominal sizes that It could be.

Sounds like an interesting project you've undertaken! Are you making your own pedal box to the original GT40 dimensions? Do you know the pedal ratios, clutch slave cylinder and brake caliper diameters? From that its easy to figure out what you need. Cheers

Thanks Ian, Yes building a pedal box. I now have the bearings. Still no information on the bore size of the Girling master cylinders, I'm sure someone out there knows, Help please. Peter
