A pillar rain gutter?

[Lenie]

I'm in need of alittle help. On my 68 firebird (camaro), I'm missing the body piece (set) that screws to the glass side of the "A" pillar that forms the remainder of the rain gutter. I do not know the name of the piece and was wondering if any of you know the name and where I could buy a set. I'm nearing a stopping point w/o them. Any help would be greatly appreciated.
Thanks
Lenie
