I just checked out the wheel codes on the plain Jan coupe my son and I are building up. All 5 ralley wheels (yes including the spare) are DG code 14x6 ralleys. Why would a plain Jane coupe have correct 1967 "SS" wheels on it? Sure the previous owner could have added these later, but with so many ralleys out there, why go through the effort of buying 5 "correct" DG's when any 14x6 would have done.
The more I look at this car, the more odd options I find.
'67 RS Coupe - Gold on Gold, 327/210, PG and mostly original
'67 Plain Jane Coupe - Penske Blue, Z/28 stripes, 350HO & Tremec TKO500
'95 Z28 Coupe - Dead stock (seriously)
