Factory BBP on 7.25 axle

Years ago the family was in route to the beach. I was driving our 73 Valiant. Other family members in their cars. I moved to the front of out little convoy for a time. Later on my Dad asks, " How long has it been since that car was aligned son ? It dog trots badly". When I said it was just an illusion he laughed it off. "Whatever you say son".
