How is the factory jack mounted?

The tire iron I have is obviously not correct. There is NO way it will make the turn to fit thru the bracket. It's difficult to see in the pics, but on my 72 the loop goes completely across the top of the mount. There is no notch like shown in the 73 Duster pic :scratch:

I've been looking thru a few different manuals trying to find a pic, but no luck yet. I'll post if I find anything for the later cars.....

I don't even know why I'm going thru the trouble of trying to figure it out, because if I get a flat tire I'm SOL since I don't carry a spare #-o :)
