Mike, it does seem that the color of the wheels on the '69 should ideally match the yellow used on the "Sunoco Camaro" lettering.
Your '67 cage is looking much more accurate now. One thought, I think the upright pieces of the main hoop should not be spread so far apart or maybe it's just that the rear angled support bars seem to be angled inward too much. There is some distance between the uprights of the main hoop and the inner part of the rear backseat area. It might be similar in that regard to the later '67 car, as seen below. The photo was taken in May '68. This may explain how the horizontal bar which runs next to the door in your model gets attached further out than the vertical part of the main hoop. A small "leg" extends over to the side of the body.
