I have a casting number of 3835590, pretty sure it is the right intake manifold. But it has a larger than normal attachment for vacuum. The male portion is screwed in to manifold per normal, the female where you would attach a hose to it are not NTP, just a bit larger than 1/4" NTP. Possibly compression? What would that thing be? Better question, how would I hook up original vacuum WS wiper motor? Am I better off to take it out and get a standard item, and where would I find one?
