The parts numbers of the various foam seals around the engine compartment, headlights, and radiator, and the dimensions of that specific foam piece under the radiator are in the pdf I linked to in my post on July 14. Looks like ordering all the seals would get expensive, but it would be easy enough to make your own after you know where they're supposed to go. I used a piece of high temp pipe insulation and squashed it into place under the radiator, it hasn't moved since I installed it a couple years ago.
