1964 Master Cylinder casting number

[Mike M.]

I have a 64 with manual brakes, the master cylinder has the 7/8 stamping on the top and the casting number 5464264 on the bottom. There is no date code on the bottom of the cylinder. I have not been able to locate what the correct casting number is for this model year. Is this an original casting or a replacement? Thanks for the help!

Base and power unit cast # 5464264 Power brake unit will have bleeder screw on the casting boss facing the engine.

thanks, I went through every different magazine article I had...but wasn't a subscriber to any of them until 2002.

Does anyone have a similar article on C-1 master cylinders?
