Here's pics of 67 vent frame(pass side). I believe 67 is unique with the bottom rod/adjusting bolt with large uclip.
I believe there is an area on lower inner door structure that clip slides onto.
In the shitty pic of my door, you can see the long screw, it's chrome with head painted black.
The adjustment bolt on the leading leg....I believe it threads into frame before installing in door?
Clip im pointing at is where vent window pivot gets clamped in. Cudas a shelf right now sorry lol. If u need more pics lemme know.
