Which models do they fit? I don't have any parts catalogues to hand for looking up numbers myself.

Hi again
Attached is a photo of the 20.6mm bore master cylinder. As you can see, it's the 3-port type, rather than the 4 in-line. Externally it looks identical to the MCs in my 83 F6 and 86 GTL. I know the bore of the former is 19mm, but am finding it impossible to measure the bore of the GTL MC in the car!
The various manuals I have seem to give conflicting information re MC bore; I know the one in the photo is listed to fit some R4s and some R5s - can anyone help with more precise info.? Also - can you replace a 19mm bore MC with a 20.6mm bore MC?

Looking forward to your replies!
Andy
