1968
ETL, In your post #3 you show the ‘67 and ‘68 Mustangs. I had a ‘67 and loved that car. Much better than the ‘65’s. The only outward difference between the ‘67 and ‘68 was that the ‘68 had side reflectors on the rear quarter panels , and a small change to the grill logo. Your picture labeled ‘68 shows the grill logo change but not the side reflector. I wonder if the picture labeled ‘68 is a ‘67 that someone changed the grill logo on to imitate the ‘68. As I recall, the reflector was a federally mandated change for ‘68 that included all cars sold in the US. In ‘69 those reflectors had to be lighted.
