I've had my '46 on the road since complete body off resto for 10 years now and only real unsolved problem is FRONT leaf springs. Newly re-arched springs cause bumpsteer, old pooped out front springs were better. All was fine until original springs began bowing in th wrong direction and breaking leaves. Maybe the monoleaf is the answer.
