The 67's got rallye wheels only with the Disk Brake option. The only thing close to a mag wheel was the 5 spoke mag simulated wheel cover. I think you could get dog dish centers with a steel wheel also in 67. As far as the steel wheels they are usually painted body color. Wire wheel covers and a wheel cover that said SS were available in 67 also. The information I gave you on the 67's came straight out of the Chevroltet finger-tip fact book printed in 67. I would say the 66's had similar wheel choices except for the rallye wheels.
