I'm always looking at different wheels when surfing around the net. Since I once owned and built a 40 Ford coupe streetrod,I clicked on this article about a very cool 40 ragtop and found these. The wheels are Team III E-T Sebrings. They look like a nice copy of the Halibrand Kidney Bean. These wheels are available in a 15x5.5 or 15x6 sizing w/3" backspacing that will fit a TG or FW. Price is very reasonable,too. If you want to up-size to a 16" rear wheel,they offer the right widths and backspacing,also.
