The condensor doesnt care the voltage. Go to your local parts store and ask for one for a cj3a. It is the same part

Here's a 1959 Auto-Lite parts catalog page for the IAU-4006-UT and IAU-4006-AUT distributors.

Keep in mind there are two capcitors in these distributors. The one before the coil (+ 24V side) is the radio noise filter capacitor. The one after the coil (Ground side) is renamed a condenser and it's only purpose is to reduce the spark jumping tendency across the points as they open and close (extends the life of the contact points).

In the above parts list IAU-1065 is the radio noise filter and IBB-2042SS is the condenser.

In the older 55/56 ord 9's the bare condenser is IAU2076L and the condenser with terminal & screw is IAU3076L. This gives you a total of 3 different part numbers for a condenser that is correct for your IAU-4006-UT or -AUT distributor. Post any of these thre part numbers to any dealers web site and their parts listing program should offer you at least one good brand name part number.

If you want to learn more about condensers just google the question "Are condensers voltage sensitive?" Here's a good discussion:
