71 Swinger wing window question

[74desertduster]

I am guessing this wing window does not belong in my Swinger based on how the mount/swivel doesn't line up?

I wonder if it's off a 4dr? I'll have to do some comparing and see.

Wouldn't mind getting the proper one unless I have to be Houdini to get it out...
