DDCOOPMAN Is correct on Speedway. However, most of the wheels they have already made up will probably be wider than you want, They also have wheel shells available that will allow you to make your own. If Speedway doesn't have them, lots of other places do. I made most of the wheels I use on my vintage modified. I mount them on the cars front spindle while that corner is on a jackstand. Spin them to make sure they run true and weld them up. I believe Speedway has wide five centers as well, but it's been a few years since I built any wheels. Speedway has a racing catalog that is separate from their street rod catalog. You should be able to find what you need on their website.
