Thanks for posting! Its interesting during this time period, many concepts/designs among several manufactures influences can be noted, and later made it to production. The 1964 clay front bumper reminds me of '69-'70 Shelby/'71-'74 Javelin. The 'aero' version's rear does '71 Mustang coupe, and the other I also see Vega and 1970 Camaro/Firebird. Another observation on my part, the 1969 Camaro's side fender/rear quarter 'lips' remind me of AMX. Interesting none the less.
