I've fantasized about shaving the drip rails and removing the wings on my 68 cause it's a Plain Jane 318. (mild custom) Duster side windows will not work because the 70 Duster was the first Mopar with curved side glass. Right up to the last minute they were sweating it out because the curved side glass requires more width through the doors for the windows to go up and down. It's the maximum curvature they could squeeze in there. I'd also think the curvature would not match the straight A pillars on the cuda.
