best bet, bet the oem number off of the carb that is on the vechile. Your local parts store should be able to locate the correct replacement with this number. The number should be on a metal tag on the carb, or stamped in the side of the carb.
Mike.C. Says; Make sure the carb is the one from the caravan engine, whenever you get any engine parts you'll want to use the model and year of the engine unless the engine is the exact same one that came out of the truck ie; 3.3 out 3.3 back in etc etc etc.... then its just a part for the 3.3 dodge Dakota... Hope this helps....20+yrs Dodge do-it-yourselfer...
