Door glass channel question

[fireguyfire]

Reinstalling the door glass in my 73 challenger after paint. I've got all the door latches, locks etc installed, as well as the regulator.
As was recommended to me on here a while back, my plan is to install the rear window track in the door, then hold the front track on the window while I install it.
My question is regarding the rear window track; I've got it bolted in at the bottom, and it is obvious where the top wants to go, but in my zip lock bags of hardware for both the drivers and passenger side there is no bolt for securing the top of the rear track.
Perhaps I'm missing something obvious, but how is the top of the door window rear track secured to the door?

Yup...you're missing the bolts. In 70-71 they use an Allen head bolt typically for those, by 73 they could be 7/16 head 1/4-20 bolt/washer

[emoji106]can't believe I misplaced them, but easily rectified!
