It probably does not matter much which vacuum chamber you use as long as it fits your distributor. The main difference in physically like chambers is the spring. This is how the unit was individually tuned for different engines. Even so, a spring meant for a different engine will probably work just fine on yours. It may have made a difference some 80-odd years ago, but now probably not. Of course, it is always best if the originally designed chamber and spring are used.

Others may have some more to add to what I have written, and their comments are welcome and may provide better information.
