To lay body on the 22s, there is a lot that needs done.
if your going to lay body, regardless of what offset wheel you have, your going to need to narrow the track width a ton. Roughly 1.25" per side. as a general rule of thumb on dakotas, if your going to lay on 22s its narrow 1.25" to 1.5 , laying body on 20s narrow .875" to 1.1875" per side.
You will have to tub the firewall on 22s and 20s. The steering will need addressed to lay on 22s , you will just barely clear on 20s.
fuel tank needs addressed to, either way.
A lot of engine bay stuff has to be worked around to lay on 22s as well. Here are a few pics of a customers truck that layed his out on 22s. Its bad as fuck, thats for sure.
