The larger diameter center link appeared in 1969. I used to think it was stronger/stiffer and perhaps a big block component. I finally got my hands on one and needed to do some modifications to it so I ground on it and found it was very soft! I think some were needed quickly and GM made a version that was larger diameter out of softer steel and did not heat treat them. I doubt they are any better than the smaller one which I think is 7/8" or 15/16".
