3461184 71 B/E/A-Body Manual Drum

This is the parts book replacement cylinder for these applications. I would assume that the part/assembly supplied to the production line would have included master, lid, bail, pushrod, plastic gasket with rubber boot ready to be installed. Because the B/E use one pushrod and the A-body another I would suspect these were 2 different assemblies.

The number on the second line of these tags would appear to be a 10,000 day calendar date. Assuming this, the one Mark posted for his 71 challenger would look to be a date that falls in for the 71 model year. The letters A, B, C could mean a number of things, shift, batch of the day, which line, etc.
