Thanks Aaron, it was a easy chop.I just added some plastic around the bottom of the rear window and made new trim,on the front I cut the trim loose and pushed it in to line up with the windshield post.
Planning on going with Lime Green and Billboard stripes all weathered and crusty. Going to use a old style Hemi. Something like this with a straight axle up front. http://www.hotrod.com/feature_stories/hrdp_1209_aaron_beck_plymouth_barracuda_challenger_design_ideas/photo_06.html
