My 63 Polara H/T weighed about 3200 w/o driver. Mega block,crossram,dana,mild 12pt cage,Will wood brakes,light seats,gutted doors,lexan 3/16 rear and side windows,glass hood and front bumper. The cage was heavy as it was originally bolted on 6x6 plates top and bottom. The seat brackets were also heavy. My new car is a 64 Belvedere post. Moly cage,seats w/ brackets are 19 lbs. Chrome moly steering column (looks stock),moly strut rods,cut down K-Frame,aluminum 5 gal cell,steel bumpers w/aluminum brackets,windshield will be lexan as well. I have removed all unused brackets and mounts. All else should be the same. Hopeing for 3000-3050 w/o driver. The vent assy's weigh 13lbs apiece if you want to run fixed windows, I like mine to go up & down. I'm trying to be as light as possible (with-in cost) while looking stock. For what its worth my buddys 65 H/T w/no cage, all steel,full interior, headers only exh, 2x4 intake weighs about 3500
