Just Purchase A 64 Ss And I'mlooking To Put Seatbelts In It Can Anyone Tell Me If Original Equipment Was Push Button Or Airplane Clasp? It Appears There Is Bolt Holes For The Front Belts, Any Ideas On Mounting Placement For Rear Seat. Any Insight Where The Best Place To Get As Close To Stock Would Be Helpfull Can't Find Any Repos For 64. Thanks
