Yep, there was most definitely a '74 Z (as stated above). My 1st car was a 74 Camaro...and if it was a real Z, I'd probably still have it. Here's another currently on
ebay.
This one also looks a little suspect (missing rear sway bar, wrong stripes etc etc). But, then again I personally think these stripes look nicer than the "mistake" decals that Chevy used in '74 anyways. And, the body tags on the '74 were very similar to the '73's and if it's a Norwood car will denote whether it's a Z on the tag.
On a side note, if you're interested in finding a particularily cool '74...look for one that had both the Z-28 package along with the "Type LT" package which deleted the Z stripes and left only the side and rear Z emblems w/ some LT badging on the side of the roof. Stealthier and without the gaudiness of the stripes.
