Looks like it is off of a 1977-78 Aspen or Volare with manual disc brakes.

What should it have been for a 70 Challenger with power boster?

Well from what I see in the parts catalog, it should be either 2944453 or 2808577.  I can't tell for sure.

2944453 is for disc brakes, 2808577 is for 4 wheel drum brakes.  Keep in mind the Chrysler part number does not appear on master cylinders.  The number on the bottom of the casting is the Bendix casting number.  The 2944453 has a 2229171 casting number casted in the bottom of the casting. The 2808577 has either a 2225601 or a 2660809 casting number on the bottom.
