    I was crawling around under the k5 today, and I noticed a metal plate that doesn't appear to do anything. It's bolted to the frame rail above the exhaust pipe on the driver side directly beneath the driver seat. I can't feel anything above it and it's not touching the t-case or anything and appears to be just a random piece of metal. Anyone have any clue what this is and what-if anything-it does?

    Exhaust heat shield. Took mine off because it was rattling.

    My 1986 K5 had two exhaust heat shields on it . One for the converter and the other for the muffler .

    Interesting, i have never seen a heat shield bolted to the frame, i have always seen them bolted right to the bottom of the truck shell itself, with spacers of course.

    Try to get a picture of it, curious.

    On my 77, there's a linkage mount for the auto trans shifter somewhere under there. Not sure if it's factory, as so much has been done to this truck.

    If it's sheetmetal, then it's probably a heat shield. If it's thicker than that...some sort of link for the trans is my guess.

    On my '87, the cat is right about where you describe the location of this plate. It's a heat shield, to prevent ass-roasting...

    Yeah, after looking at it some more, I got pretty convinced it was a heat shield. I'll try to snag a digital pic and post it. Thanks dudes.
