Very possible the sub frame was swapped. I know mine was after a crash by a previous owner. 67's and 68's are interchangable
Yeah. My car was a parts car for a guy who was building another Camaro. I know it's not the original frame. It's not the original front sheetmetal either. The doors and deck lid are original...but that's beside the point.
The reason I would like to check the frame for some sign of production is because the CRG states:
"Subframe style: A mid-year change was instituted for 67 Camaro subframes. Large holes (about 3-inch dia.) were placed on the inside surface of each front frame "horn" to provide access to bumper bracket nuts.
The earlier frames used a slot in the outer surface of the frame horn to hold a J-nut (clip nut) for the bumper bracketry. The transition period for this change appears be circa November/December of 1966; we are attempting to gather more data to further refine the implementation date. An interesting note is that some frames have been found with the large hole on one frame rail and none on the other rail. Apparently such frames were built during the transition period from one style to the other, while making use of all existing frame stock. If you have a Camaro built from October to December of 1966, we would appreciate your car data, via the CRG Forum, including a note on which frame style you have."
My 67 frame has one of each type of frame horn, which could possibly be right at the end of the change-over before production ran out of the early style stamped frame horns. If I can somehow determine what month my frame was made...it could help the CRG narrow the search on the subframe switch-over in late 1966. If only my car was late 66 production Camaro...
