I'm actually thinking of taking 3/4 of an inch out of the a pillar and a pie cut out of the c pillar to get the roof level when she's on the ground But if I'm cutting it I might as well chop the whole thing 3"
I personally like the suttle change of 3/4" makes the car look good, the 3" chop is to over the top and obvious. I'd have to see it to determine how it looks on a duster. Good luck
