My own internet searches this evening did not find the drawings I had found 20 years ago. That said, the design was patented by Ford and was sought after by Chrysler, I think AMC and BMW or Mercedes.

I believe the best source for the significant portion of the design today, is probably the US Patent and Trademark office. The original patents detailed and described in words and drawings the special attributes of the design necessary to get the patent.

My notes indicate the patent number was US3189118 and I want to say it was filed in February or March of 1961 if that helps. I think there may have been revisions and refillings to cover the revisions. The original patent number should put you on the trail however.
