I have some seat belts which need indentify-
ing. The buckles are color keyed to the interior
There is an embossed "bow tie" in the center
which is not painted. Any ideas as to what year?

See if there is a white tag down near the end that goes on the floor,if its still there, there will be a manufactured date on it.Sounds like a sixty four .the sixty threes had a silver buckle and were dealer installed whereas the sixty four could be factory installed.
