Replacing the Steering Wheel Edit
johnarleyburns on the DMCTalk forums has written a good step-by-step guide covering how to replacing the DeLorean's steering wheel. The guide includes instructions for removing the original wheel and installing either a DeLorean wheel or an aftermarket wheel, both with and without an adaptor. The process is fairly straight-forward and requires minimal tools..
The stock DeLorean steering wheel is 13 inches (330 mm) in diameter with a Momo-style mounting. It is recommended that you use a replacement wheel of about the same diameter to ensure that you can still easily fit your legs under the it when sitting in the car. If you want to use an aftermarket wheel without a Momo-style mounting, you can buy a Momo adaptor from DeLorean Motor Company, Texas, part 111396, or through other vendors.
