Car 70 Duster with ralleye mirrors--When I restored the car I put on a ralleye remote drivers side mirror,Now three years later I wanted to put the second mirror on the passenger door before I headed to indy,So I ordered one from Vans auto here in wis. just got it and at first glance it seemed bigger than the drivers door mirror,When I took a tape to it the drivers door measures 5.5 inches across and the new passenger side measures 6.5 across so I called them and they told me that it is the correct mirror that from the factory the mirrors were 2 differant sizes- Can someone please let me know if this is correct before I mount the mirror,Makes no sense to me but if this correct I'll move forward--Thanks Steve
