I figure Z/28 with that flat hood and the stance which screams 4 leaf suspension. In fact I'd bet on it being a 52B X33 car myself.

The only options that had mandatory bumpet guards that I'm aware of are the Z28 and G31 rear spring option which included v32 rear bumper guards. You could have just ordered V32 bumper guards as well. Looks like a flat hood so most likely a z28. Not sure about the pinstriping...

A friend of mine had an October '68 built RS Z back in the '70s and it had the pinstripes.

Agreed... flat hood '69 Z

Dependent on other options and when the car was built. For example very early in the model year a Z/28 with Z21 would have been built with D96 striping. Chevrolet quickly revised that. An update to the Showroom Album dated September 12, 1968 states:

"FENDER STRIPING (RPO D96, Body-side accent stripe) included with Rally-Sport and Style Trim Group. Not available with Sport Striping (SS or RPO D90). Available in combination with Front Accent Striping (RPO DX1) or with RPO Z28."

The January 2, 1969 revision further limits D96:

"Not available when Camaro SS, Special Performance Package or sport striping is ordered. Included when Rally Sport or style trim is ordered."

The car in the photo has the 2nd design head restraints and appears to have a '69 rear spoiler. To have all that it would have had to have been ordered late December, 1968 and built mid-late January, 1969.

Id go flat hood Z/28, vinyl top and it has Z/28 bumper guards in the back i believe

So it could be a d80 car, pipes could be chrome as per the later cars after may of 69

looks like it has one of the dealer or gas station service sticker in the door jam as well

did they ever put these service checklist stickers on the car when they were new??

It looks like an early Z/28 with the short rear spoiler, flat hood and I do not think the exhaust tips are chrome.

The tailpipes do not appear to be chrome. Both rear spoilers were used in production starting mid-January through early March. Vintage photos show early production Yenkos with the '69; ZL1 #3 has the '68 and was built on or about March 4th.

If the car in the photo was built with D96 striping it had to be ordered prior to January 2, 1969.

Flat hood would suggest Z/28, no?
