Sounds like it's a 67 console. With the ashtray at the back end, and the slotted light on the back end itself. These cams in the camera grain finish in either black or the interior color of the car. They had a drop two piece plate for the shifter. Same for Camaro's

The 68/69 console got the BurlWood treatment, no ashtray or light and the shifter section differed. Auto mounted on top of the console and was a one piece plate, while the 4 speed was the center section with the shifter tunnel so to speak, all one piece.

The basic console under the wood grain plates is the same for 67/68. It even has the chrome trim and camera grain etc... so you could get the top pieces and turn it into the 68... and you may just be missing the rear piece is all? Is there a light on the back of the console?

If you decide to get a whole new 68 console at some point, I'd be interested in looking at yours.

Good luck - Brett - 67 Drop Top 455!
