67-72 factory sway bar sizes thru the years/options

So if they were upping the size from 67 to 69 and the 69 bar measuring at 0.95” is the biggest, is it safe to believe it was the only bar carried up thru the 72 model year until the 73 K frame change? From what I also gathered the part number changed twice from 67 to 69 and then remained the same thru 72, unless I misunderstood what I have read so far.
