Can anyone tell me what the bore size is for the OEM master brake cylinder that was used in a 1970 Mustang with Power front disk brakes? Not sure if they are different for power vs manual but I suspect not.

Thanks!

Bore size is 1".
To my knowledge, in 1970 they had the following brake options:
Manual 4 wheel drum
Power 4 wheel drum
Power front disc, rear drum.
