There are 3 different deck lids for the 67 Camaro alone, depending on when the car was built, different punchings and inner brace configs if you are doing a "100 % correct" restoration. If this is the case please advise build dates and we will try to direct you to the version that was in all likelyhood on your car when it was built.
HOWEVER
If you just need something to fit and fit well then the HBC lid that's about 450 or so is the way to go. The cheaper versions are no where close to correct and you will spend more than the difference in frustration & time.
