Seems as though everybody has a different method for making their own boxed lower control arms for a rear sway bar application. I have a GM sway bar for the 67 Chevelle. Does anyone out there with a factory installed rear sway bar know what the hole locations are in the lower control arms? As measured from either of the bushing centerlines? Any pictures out there of a factory mounted bar? Thanks

Tuck, I have a 67 malibu that was converted to boxed lower control arms and sway bar at some point in its life. The measurements are approx. 6 inches and 12 inches from the outer curved rear portion (around the bushings) and 1-1/4 inches from the top of the control arm to the center of the holes. Hope this helps.
