I used a mirror out of a 5.0 mustang convertible but the same mirror can be found in other makes of automobiles. Be sure to get the mirror, metal attachment that glues to the windshield and the plastic cover that covers the wires coming from the headliner. Since you have a convertible I suspect you can route your wires under the stainless top header since you have no headliner. The mirror attaches (glues) to windshield just like the stock one does. The mirror I got from pick-a-part had the same shoe as the stock '70 mirror but I don't think it was mounted the same distance down from the top as the '70 mirror was. I installed a new windshield so I'm not sure of the measurements. I like the fact that you have an overhead light source when you get into your car at night. I seldom used the map lights but they are there when needed.
