Tom, the only difference for AMC applications is the activating arm. If you had your old original pump you could swap arms with the new one and be fine. I believe the pump will swap with Chevy sixes also, but not 100% on that one! If the make is the same you can probably swap the arm from your non-booster pump. You'll have to take a close look at both to determine if that can be done. 

In your case I don't think I'd try an electric vacuum pump just yet. Go to a salvage yard and look under the hood of 90s Ford trucks or Crown Vics and some big GM and Chrysler cars. You should be able to find what looks like a juice can under the hood. The big half gallon size would be best (about 8" long), but there are also quart size cans. There will be a fitting on one end with two hose barbs. You should be able to suck on one but not blow into it (has a check valve). Connect that one to the intake manifold, the other to the wiper motor. This storage cannister should provide an adequate boost for the wipers for at least 30 seconds (small can) for accelerating or pulling up a hill. At least the early four cylinder Jeep Cherokees also use the small cans. 

Some cars use a plastic ball storage tank. Easy to spot -- has two hose barbs with vac lines on it. Those are no more than quart size, I think a little less. The tin can just looks more "period" under the hood of a Rambler, so I avoid the plastic balls.

Unfortunately, I do not have the correct fuel pump to fit my 232. It has a fuel pump that  (I assume) was made for cars with electric wipers.
 I did buy a fuel pump that was supposed to fit and it bolt up just fine, but the arm was slightly different. I couldn't really tell until I hooked up. The cam was hitting the arm, but was not pushing it up enough pump fuel or air. That pump was almost $100 and I didn't get to putting it in until 4 months after I bought it off ebay, so there was no returning it.
 I'm wary of buying another one off line because they are expensive they all look a like or at least like the one I tried to use.
