280zx ignition lock and switch replacement for Roadster

[Mackn367]

So I followed the tech wiki on the 67.5 ignition lock / switch replacement and bought the 280zx one I found on Ebay which was a great price. Got the part and the metal bracket that goes around the steering bar was too large in diameter. In doing more research I found out there are actually TWO different sizes. The large size (1 1/2) was too large. I now ordered the smaller size (1 1/4) which I believe is the correct size diameter. Just an FYI if anyone plans to change their entire ignition module to make sure you buy the right size
