You are correct, the same 2-1/4" button steering wheel is listed for 1963 - 1975 CJ3B, CJ5, CJ6 and FC models, but it is the same reproduction Crown wheel without the snap ring groove. I bought one several years ago when I first got this jeep, and, although the horn button would fit, I was not happy with the gap between the button and the wheel. While I was removing the steering wheel prior to removing the body tub, I damaged the bottom of the wheel and will need to replace it again. I was hoping to find one with the groove this time. Thanks all!
