Hope you are well. Chris Flatmoe here. The wheels on my 69 Camaro (not mine anymore) are in fact Billet Specialties GTX -01. Here is a link to the wheel in question:
Thanks Chris, I thought that's what they were. They look really good on that car. I have a blue 67 camaro and I was considering buying those wheels. You don't by chance still have them and want to sell them do you? I don't have any tubs on the back of my car. Do you know what the widest wheels is that will fit on the back of a 67?
