1972 Duster Door jam switch's

I need a set of door jam switch's for my 1972 Duster, the one's I've ordered from year one are to small for the opening all ready made in the door, once I find the right ones I will sell the other here.
The part number for the wrong size one's are NG1031 ( Says 3/8" Size ) but I need a bigger size. Not sure what to order, I've even seen some that have two spades for wires but I think I only need the ones for one wire.

Please help...
