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...

interesting, i just had a conversation with another member about a month ago, exact same issue

I'm dealing with the same issue myself on a '73 Duster. I ordered one through autozone and it's too small to fit the existing hole. I took it back to the store and they looked it up to confirm it was the correct part listed.

Looking at how the switch works, I might just try cleaning corrosion off the contacts of the existing one.

Ran across the same thing a few years ago, where they were all too small.
I finally just gave up and got some spacer sleeves (like a threaded insert) from Ace Hardware, since all that is required is that the switches ground to the body.
Been fine for years now (and why wouldn't they be?)
