Ok gang I bought a 2000 express 1500 passanger and useing her as a light delivery van van runs fantastic and all but I want to put a set of rims on it. Neighbor I have has a set of 18 inch rims off of an impala everything says they will bolt onto my van what I'm wanting to know is if the offset will cause problems and if the center bore is the right diameter dont have any tools to measure with so I'm looking to you guys oh my van has the old big bolt pattern
