    Working on restoration of my 81 C20 suburban. Question about the radiator. I have an intact core support and the full upper radiator panel and a full shroud.

    Aside from the rubber feet, is there anything else that holds the radiator from moving?

    On my '85 the radiator is only held in by the 4 cushions and the top plate.

    So the shroud ties it together and that’s that? Thanks so much.

    And the top plate as Craig just mentioned...
    They are not all the same, depending on year and such. Kinda makes like a clam shell pinching the rad that sits in the rubber feet. The rad needs to float around a bit, not mounted solid.
