if you need new clip wheels you will need to have a set made at stockton wheel.
http://www.stocktonwheel.com/ you will need to have your desired wheel width and backspace and know if you are/or plan to run disc brakes. they will build anything you ask for.
an option is to order new wheel vintiques wheels from summit or jegs. you can also order new wheel vintiques caps that will work with the new wheels. pay attention to the cap style the wheels you choose will take, there are i think three different types of the same chevrolet stainless cap. you can get them in smoothie style, which i love myself, or artillery style, which I have also used, or the gennie style wheel that I have used too. you can click my name and look at a couple of my trucks in my gallery, anything that is steel with a stainless cap is a wheel vintique product.
