I have a set of the Cobra replica wheels left over from a past project. I tried the 7.5 wheels and the is an issue on the front of an Avanti. The width will not clear the outer tie rod end. I even have shorter steering arms on this car. My solution for the future is to narrow the front wheel to 6 inch in width. In the past, I have taken this style wheel and have had it widened for customers to a 13 inch wide wheel for GT 40 replicas.
