There's only one classic Mustang steering wheel in my opinion - Mota-Lita. This was standard issue on the Shelbys and is the finishing touch to your Classic Mustang interior.
The 15" Dished teardrop (mk4) is a close version in leather. The Shelby steering wheel is wooden. Both are dished. If you're looking for a steering wheel for your Mustang, then make sure you get the boss too! If you don't get a dished wheel and go for a flat one, you may also require a spacer.
The steering wheels below are original Mota-Lita and considerably cheaper than buying direct!
