The Road Runner has the original Disc Knuckles it was built with in October 1970.
The offset bushings were installed to have the maximum caster. The front bushing installed as per the MOOG directions with the thin rubber sections close to the engine. The rear bushings are in the opposite way with the thin spots away from the engine.
I am a carpenter, used to inches and fractions. The alignment sheet is in decimals. Still, the camber is something like 0.6 degrees POS on both sides and the caster is less than a degree POS.
I've been wondering why I had such good luck with my car and he has not. I've been under the impression that we have the same knuckle/spindles, but mine are from a 75 Dart. Maybe mine have some camber & caster advantage???
