This is a NOS Front Shoulder Seat Belt that is Green, the belt is code dated 44 - 71, it is a Deluxe Buckle. I only have this one as pictured. I do have another Green seat currently on another Ebay listing, it is a Rear Belt with the same buckle and also NOS.
This Belt is correct according to the numbers to fit the following cars:
1972 Pontiac "A", "B", "G" & "X" body cars except Convertibles.
Also it is Correct for 1972 Chevelle except Convertibles and El Camino.
The Buckle was made by "Hamill" and the model is "RCF - 65".
