Need seat belts for 1963 Coupe Deville

[rwils]

Looking for original light blue front seat belts for a 1963 Cadillac coupe deville.  Webbing needs to be the light blue type color, faded OK.   I actually have 1/2 of each front seat belt, the 1/2 with the buckle and that is attached to center floor.  So I just need the 1/2 belt that attaches near the doors, and inserts into the other half with buckle.  See attached picture of the belt/buckle 1/2 I do have, and picture of where the belt 1/2 I need attaches near door. 
Thanks

While you could get Cadillac seat belts in 1963, I am quite sure those are aftermarket belts based on the buckle and the belt webbing.  Gas stations and other repair shops did a land-office business back in those days installing aftermarket belts when the seat belt craze hit.  I put a set in my future mother-in-law's '62 Impala convertible back then, and delivered them by the dozens to the gas stations my father supplied as a Chevron wholesaler as part of my summer job.

You are probably correct.  If I cant find older seat belts vaguely matching these, I may just get new ones from Andover, unless anyone has another suggestion.  Thank you.  R.Wilson
