Do any of you think that RMS, Magnum Force, or whoever was the VERY FIRST person to ever make a bolt in K-member? Using some logic expressed here, it would seem every one is a COPY of somebody's. Hot rodding is seeing a market and improving upon what is available in that market. Why is it a direct copy? Because it is square tubing? You only have 2 choices, square or round. So if it was round who's would it be a copy of? The upper shock mounting is not remotely similar.
