I had a set of 41 and a set of 46 headlights when I got my truck, one of each on it, with one 46 parklight and one 41 , my truck is a 41 but the othe 41 headlight I had was in bad shape so I had a shop make the 41 parklight fit the 46 headlight bucket, confusing I know, but 42-46 is the same, 41 is the odd ball with two piece park lights and the 42-46 being one piece.
