My name is Ed Wallace from Ga.. I have just purchased a 67 coupe that I found on this site. The car has drum brakes. I have done conversions on other cars in the past so I have the tech knowledge for the swap. However while searching for conversions have seen alot of 2" drop spindles and I wondering in doing a drop will this hinder tire and wheel options. I am considering either 16" front with 17" rear or 17" front with 18" rear. Thanks to Team Camaro your site has been extremely helpful.
