I have just installed a NOS switch in my 70 Mach wheel and there is about 3/4-inch overlap. I tried it in a 71 rim blow wheel from a full size car with deluxe interior and it mounts the same. The box reads D1AZ - 13A875 - A. Is this the right switch for a 70 Mach or am I installing it wrong? I am starting with the connection in the same place as the original I removed and working it around the wheel. It overlaps approx. 3/4-inch onto the piece I start with. Thanks for any help.
