Has anyone used a wheel spacer to fill in the rear wells on a Duster?

It does take a lot to push them out there far enough to look good. The best way I have found to determine the size of the spacer needed is to tie a washer or nut to a string creating a plumb bob and tape it on the inside of the fender liner at the farthest point out that you would like the tire to travel. Then just measure the distance to your tire sidewall.
