I did try the alum wheels off the wifes 01 Grand caravan on my dart for sh1ts and giggles. They looked pretty good. I have a b-body 8 3/4 rear. only done it for a few minuates and I cant remember how close it was to the lip. Heck I may have to try that again and get some pics.
yea your 01 Caravan wil be the 4.5 pattern and should work if the offset is ok. I tries wheels from my wifes 96 Avenger and they worked ok on my 65 Cuda.
