I’ve been researching Cougar / Mustang forums about 69/70 correct master cylinder and lid colors. Some say the the master cylinder and lid are painted black. I’ve seen it said no their natural steel color with a zinc or gold lid. Find it hard to believe there are differences with the Mustangs and Cougars. Is there differences at plants or different manufacturers of the master cylinder. Thanks!
They were spray painted together in a semi-gloss black. Have a look at this section from Dead Nuts On ( True Concours Reproductions ) on the Master Cylinder and cap:

Thanks for the info.
