Front Sway Bars
how the original sway bar mounts has nothing to do with the engine size. my 70 duster /6 had the hd suspension from the factory and had a sway bar. the aftermarket bars use the shock hole to add a mounting bracket for the endlinks. personally, the firm feel has the bar to frame mounting down pat. great design. the PST isn't much to write home about. their brackets hang down too low with the L bracket design. just my opinion.
