I found a good deal on some 07 factory 20s from a 1500 that were on a 2wd truck. Will these work on an 01 1500 that is 4wd? Here's a link to see what they look like http://www.southeasttexas.com/classi...de=&distance=0

 

Think you need to grind out the hub centers on the wheels a bit for them to bolt up nice. But, do it once, and you are golden.

 

I have 20's from a third gen on my 2001 and they fit just fine.. the rear were snug going onto the ring on the brake drum but I didn't have to grind anything.

P.S. your link isn't working anymore so I can't see exactly what rims they are so YRMV!
