door jamb switches

I need a set of Door Jamb switches as pictured below. The bigger ones on the right. They have a 1/2 " thread size and a 9/16" hex size. One on the driver side is a 2 prong switch and the one on the pass. side is a plug in type. They are on my 73 Dart Sport. One of the members here said he has them on his 72 Duster. I need the 2 prong one the most. The pass. side may work. would like to find them new if possible.
