67-72 Front Sway Bar

@Sdriche , even though this stabilizer bar is a long "limber timber" with long end links that lose a little response there also... If your 68 doesn't have a stabilizer bar at all, you want one! I've owned 2 of 67model slant 6 builds with no OEM bar over the many years. Sure the V8, disc brakes, etc., made a difference. The stabilizer bar made the most difference. No more sliding toward the passenger's seat.
In my day I had to get the lower arms with the tabs when I got the bar (at a part yard). Today we have alternatives as posted above.
