    ‘83 K5: Confusion with ordering the right grill. Please help!

    Once again I’m needing assistance with my ‘83 K5. See pics. The black grill is what I removed during my restoration.

    ‘83 K5 Restoration- where do these parts go?

    On my ‘83 K5 restoration I apparently didn’t label these parts during tear down. Can anyone tell me where these parts are installed? Typically, if/when I don’t label a part is because it would have seemed to be obvious where it goes but I can’t remember on these. Thanks, as always!

    Please remind me where these old/removed parts go on an ‘83 K5.

    I can’t remember where these parts go. Obviously they attach on each side of something since they are symmetrical. They look like window channels but I’ve already rebuilt my doors and tailgate. Could they have been superseded by a new design that I’ve already installed? Please provide an exact...
