Looks like you've decided to stretch the roof, but for what its worth heres how to lean the pillars- To tip the pillars take a sawzall and cut from the middle of the curve of the winshield opening and from the middle of the curve of the door opening to a point that forms about a 90 degree angle between the two points, but dont cut all the way through, leave about 1/4" in the middle to pivot off of. do this on both sides. Then take the sawzall and take a notch of the bottom corners of the windshield frame into the a pillar to lean them to meet the top part of the pillar. Make sure the cuts are the same one both sides so it doesnt end up looking lopsided. heres my 52, 3" chop 4" section, leaned back pillars http://img.photobucket.com/albums/v395/52pickup/DSC00584.jpg
