[VAL] Plastic trim?

[Dave Lowrey <airstream@xxxxxxxxxx>]

In my Argosy, the aluminum inside skin has a plastic "trim" on the edges 
where they meet the front windows and where they overlap each other. The 
edge you see is about 1/4" wide. the edge that is behind the metal is 
about 3/4" wide.
You can see a photo of it here: http://www.pfredd.com/airstream/edgetrim.jpg

Also, there is another plastic trim piece that runs along the front that 
covers a metal track. It is about 3/4 inches wide.

Any idea where I can buy these?
