Wheels, tires, and brakes

Hi, my friend wants me to get an extra set of wheels for her 03 Grand Caravan to put snow tires on. I am getting the rims from a junkyard but since newer vehicles don't end up in the junkyard that often I was wondering if a set of rims from a 97-00 caravan will fit? I am sure they have the same lug pattern. Also, her van curently has 16" rims and I wondered if 15" ones will have a problem clearing the brakes? I asked because this van has two diffrent front brake rotor part numbers availble. I googled but can't find the info I'm looking for.

Gee, thanks a lot guys! If anybody else needs the info I will provide it. There is no way the 97-00 Caravan wheels will fit an 03, the lug pattern is the same but the center bore on the 97-00 is visually to small to fit. I snagged some Intrepid wheels instead and while I haven't tried them on yet I know the lug pattern is the same and the center bore is big. Aside from these wheels being 1/2" wider I think they will fit.

Yup. Apparently none of us had a clue. I've been on this forum 4 years and have rarely seen posts related to wheel compatability. In fact, anytime a question comes up about parts compatability between vans, especially between generations of vans, few if any answers come up. Maybe there's just not enough people out there familiar with the subject. Anywho...thanks for passing the info along. It will eventually help someone somewhere.
