Window sill part question

[jcwhidby]

Good afternoon everyone. I am trying to find replacement parts for what I would call a "window sill" but I am having trouble locating a replacement. Does anyone know what the proper description is for this part and where I could find a new new one for each side? Thanks!

There was a fella on here that did a nice restore of those windows seals. I just can't think of who it was at the moment.

I need to deal with mine too.
