The alternator you're after is from an '88-'91 Dodge Dakota, D-series truck, or B-series van with a 3.9 V6, 5.2 V8, or 5.9 V8; or an '88-'89 M-body (Diplomat, Gran Fury, New Yorker Fifth Avenue, or Canadian Caravelle). It has the V-belt pulley you'll need, and electrically it'll hook up to any earlier Mopar regulator. If you're using the '70-up electronic regulator, just connect one field wire to each of the new alternator's two field terminals. If you're using the '69-down regulator, connect the one field wire to either of the alternator's field terminals, and ground the alternator's other field terminal. You will need to do some bracket adaptation, purchase new brackets if you're running something other than an LA engine, or use the '88-'91 brackets if you are running an LA engine. You will also need to consider the effect of this alternator's higher output on the rest of your electrical system; see this post and here for more info.
