I have heard of a 67s or 68s made with a 2 speed rear axle. Less than 500 of them made. Was it just an option or was it part of a package? I am wondering what kind of axle it was, disc or drum, how wide, what axle ratios in both speeds. There might be only a dozen of these left. How hard would it be to find one of these axles?
