67 Z-28 ...missing rare shoulder belts???

[iluv69s]

I always thought the interior on my 67 Z is original...but after checking the CRG site of the shoulder belt option(Thanks Kurt), I realize I am missing the shoulder belt clips that mount on the rear panels. There is no evidence of there ever being shoulder belts or clips on the car.

f.y.i...the car is a cowl dated 07C 67 Z-28. the latest cowl dated 67 Z known to exist.Also a few hundred VINS from the last 67 Camaro built at Norwood. The car shows 17k miles and I always assumed original because of the condition..especially the interior and original carpet, seats, panels, etc. The only option on the cowl tag is the Z-28, 4 speed and 05C..the ultra-rare shoulder belts..only 477 made(I believe)..less than the 602 Z-28s made..

Is it possible the car was shipped without the belts, as being so late in production?? anyone else have a 67 with 05C code and no belts?? Thanks..max
