Has anyone put the rear end under the leaf springs (move the perches)? Right now my dart has the rear on top of the leafs. I want to raise the rear some. By doing this, the rear would be raised by 4". Right now the wheel well is even with the top of the wheel (rim). It looks like a lowrider right now. Not a look I like for a dart. I know I can buy new leafs, but I am wondering about the above modification. Will it pose any problems, and what might they be?
