Dunno, but if you go on to Tire Rack and put in a Pacifica and an older Caravan and look for wheels, they'll tell you....

nice idea, but no joy. tire rack will tell you the dimensions of the wheels, but not the spacing/diameter of the lug nuts.

But the ones they give you will fit.
If the same wheel will fit an older caravan and a Pacifica, then the bolt pattern has to be the same.
