I have a set of 4 wheels for sale. These are made by PS Engineering. They are replicas of the ones used for Trans Am Racing in the 60's by the likes of Jerry Titus. They are 15" x 8" wide with 4.25" backspacing. They are brand new, never mounted. I paid $1,200. Though they look simular, they are not the American TTD's. If you are looking for that vintage Trans Am Racing style, these are as good as it gets. As far as I know the only person that makes these is Phil Schmidt. I would like $850. which include 3" lugs and center caps.
