You can start by checking out the sticky topic of the wheel fitment database. Plenty of '67 Camaro info there to get you within range. Since you have a sponsorship, why not get a wheel template or fitment tool to see what rim widths work, then work with your sponsor to give you the backspacing you desire for the wheel lip you're going after? Your specific fitment requirements will require proper measurements.
