I was looking at the date code as well after my post, J168 is 10/68, Keith check the vin and the date code again. That casting number may have been carried over to 69, I am not sure. Run a PHS like Pete mentioned. The VIN would be 242379B164939 for a hardtop or it could be 242679B164939 for a convert.
It would be cool to find out if it is for a automatic RA III GTO or a Judge. Plus you would lay to rest what it actually is.
