Dennis both pictured Novas are actually a 1962 nova,...
easiest way to determine 62 thru 65 is the grilles, also the 62 chevy ornament on the hood was short like on the white nova
1962,...3 verticle bars with one main horizonal and several smaller horizonal
'1963,.. grill is easily recognized with only horizontal bars.
1964,... resembled a checkerboard pattern, with 9 verticle bars seperated by 5 horizonal bars.
In 1965, a distinguishing headlight assembly. This is the only year this syle of headlight would be used. The light bezel consists merely of a chrome circle and a small eyebrow strip. The grill is much like the '64, but spaced out a bit more and with a new emblem adorning its center.
