73 Scamp Door Window to Slide Nuts

[chickendeluxe]

I usually work on earlier B's so no parts in inventory.

I was missing the nut on the Front Side to Glass on my Drivers Door.
There are I think 5 total holding the glass on.
Removed the glass and looked at the manual and parts suppliers.
What year did they start this nut? Gonna hit a junkyard tomoorw where they have 3 4 doors there.
Do you use snap ring pliers to tighten?

Thanks in advance!
