Pete: I can't swear to the authenticity of the belts in our K conv. as they do not have the Chrysler part number tags on them. But, they are a mix of identical-looking belts from our K coupe parts car and the belts that came with the K conv. The front belts are affixed to the floor with hex-head, shouldered bolts that thread into factory-installed sockets in the floor. I've attached photos of the locations for the front seat belt connections on the raised section of the sills and driveshaft tunnel. I understand the threaded sockets may have been sealed with a removable rubber plug in cars without seat belts from the factory and that makes sense as they would otherwise provide a direct opening to the roadway below. There are two pairs of similar threaded sockets on the kickup area of the rear floor pan for rear seat belts. I think the bolts were high-strength and the threads were fine. The floor end of each front belt has a triangular steel plate with a large round hole in it that fits into the shoulder portion of the bolt and a narrow slot through which the belt is looped and then sewn in place. The latching hasp is quite plain-just a flat chromed buckle that lifts to unlatch from the other chromed-steel belt end which has two square holes in it. The outboard front bucket belts are retrieved into a plastic holster by a little windup spring. The center belts just flop around loose to bang up the aluminum on the console. The belts are labeled Hickock brand-- P.G.-12171-1. Similar-appearing belts are readily available-mights well get the proper end connections defined and purchase accordingly. The hardware and belts retrieved from the back seat of the coupe were all hook-type belt ends connected to the threaded steel rings. Original belt connections and design may very well all have been ring-topped steel bolts threading into the sockets and the belts being attached to the rings by the hook-type end connection. And the belts would carry the Chrysler parts tags with part numbers on them. Data I've seen indicates there may have been two different types of belts, perhaps retractable and non-retractable. Color-coded or not. The data indicates only front seat belts were available from the factory. Dealers could apparently furnish and install front and rear seat belts at or after delivery. Perhaps more learned folks can advise what the front and rear original '64 Chrysler belt floor connections were. In any case, the sockets are there for four sets of belts and I believe the floor is reinforced on the underside in those areas. I remember being told that there would not be a concours-judging penalty for seat belts, factory-installed or nay--so long as the buckle and belt design were similar to the plain originals. No gold-plated Cadillac buckles on multi-color webbing. I just saw some statistics on the burgeoning vehicle death rate in CA. The CHP indicates that over half of the fatalities were not wearing seat belts. It may just be the same folks that drive under the influence reject other rules such as Click it or Ticket. Belts of proper style and connection should be installed and used in all positions on every 300 made (and all other motor vehicles, of course).
