I would be concerned about a difference on a replacement . You may get lucky and get a similar from your mentioned  "currently available" . And maybe you will not. Better to be safe then sorry IMHO.  Booster Dewey is who many use to rebuild their Bendix boosters. He is known for good turn around.

+1  Sure would not trade it in but would expect that something bought at the parts house would be different and lack other details

I would try and get it repaired as the first option as they aren't complicated. Parts aren't a problem it's just a matter of finding the right person.

One thing to consider when purchasing 1969-70 brake boosters is that the assemblies do not interchange. The push rod is the determining factor. mis-matched boosters and pedals will cause diaphragm failure fairly quickly. It is not uncommon for sellers to identify the assembled boosters incorrectly, or say that they fit 1969 and 1970..
