[Jim's rare 80]

Hi. I owned a 73 for many years. The driveline is now in my 80. The only things the same between 73-74 bodies are hood, doors, and trunk lid. Rear quarters, rest of front clip, even headlight bezels are slightly different. The rear glass could have been the same, depending on model. The supreme had small quarter windows, and a bent back window. The Cutlass "s", or salon, 442, had more of a fastback stlye, with longer quarter windows, and a flatter back window. If you are looking at a parts car for your 74, a 75 would be closer than a 73. Hope this helps. Jim.
