So in 67 did they still have the option for the spinners?
No, they didn't. One of the first MVSS (Motor Vehicle Safety Standards) regulations in 1966 (sponsored by activist Ralph Nader) banned "winged projections" on wheels or wheel covers, as he felt that it constituted a hazard to pedestrians.
BTW, no true Corvette knock-off wheel ever came off if it was installed correctly; people didn't read the instructions or let tire shops who didn't have a clue take them off and put them back on, and that caused problems.
After 1967, sets of Corvette knocik-off wheels sold over the parts counter came with large hex nuts instead of 3-eared spinners, and a box-end wrench to whack with the knock-off hammer - see photo below.
