Looking for a 67 J52 master cylinder for a 67 442

67OAI

Is there a particular casting number that you are looking for....and what would that be?

66 W 30

I believe part number is 5459784 or 5462217 and the code is SK:

Note how the overall cylinder shape and cap retaining rings are different than drum brake cars (pictured below)
