Jeep 4.0 in 69 Barracuda

Has anyone had to work on the rear window regulator system? Mine was spaghetti and required cutting out and replacing. The one I got had bad grommets on the bolts which hold the glass to the brace. Which is still better than what I had which was nothing. I was hoping I had workable items.

With the car leaving in under 48hrs, I dont have time to purchase the correct ones. Does anyone have any ideas what I can use to hold the glass with out damaging it?
