question . is there a difference between steering arms for a drum brake and a disc brake front end . bolt pattern . i thought they where the same until later on when they went to the larger pattern .steering arms . like mini truck . just asking because i notice steering arms being sold on e-bay saying they would only fit drum brake axles only . so if that is true does that mean there is 3 different bolt patterns for the steering arms ,drum arms .small pattern disc arms ,and large pattern disc arms like mini truck ?
