Does anyone know what all you have to do to swap the narrow quadra trac system to wide. Are the axles the same for quadra trac as they are for the other types of 4 wheel drives? I have a 76 cj7 quadra trac and the dana 30 went out and I found a dana 30 wide and amc 20 wide out of an 85 renegade but just don't know if they will work and if they do what do i have to change.
