Glass Holders

[NH_ Pellet]

I have a new to me 2006 Castile Insert that came with the glass side panels for the side castings, but no backer plates. I believe the backer plates are available on line. But how does the backer plate attach over the glass to the casting? There are 4 nubs sticking out of the casting but I don't see any type of attachment method
thanks Tim

In case this helps someone else. I found out that the backer plates are held on with speed nuts. So I'll pick up a few at the hardware store and shouldnbe good to go
