Part at bottom of side window glass

I need to replace the metal channel that holds the window glass in my 76 K-10 but am having a difficult time finding it. Mine is rusted out. Does anyone know what it is called and how the glass is held into it?

Pic attached is not from my truck, just an example.

That is called a window sash

Urethane or the Right Stuff adhesive RTV works

I tried to order the window sash for both sides twice and the part was not right both times. The parts I ordered were for a much thicker glass. I went ahead and sanded mine down and rust treated it.

73-80 glass is thicker than 81 up and there are 3 different window sashes but basically 73-80 and then 81-87(91) is the split
