Sunroof part

[Robert Deis]

 Hey, all.  I have a couple broken sunroof parts on my 86 5kTQw.

They are the plastic parts that screw to the sunroof panel itseld, each
one is about 10" long by 1" wide by maybe 1/4" thick, with a couple of
long slots cut in them.

Are these the unobtanium parts I've heard about before? (I don't have a
part number reference yet..)

Has anyone considered making some of these out of aluminum? THe design
seems very prone to breakage, especially using plastic..
