    Replacements for rear induction grille gaskets?

    Hey all. So these gaskets seem to be NLA, and nowhere on the parts diagrams. Theyre made of that injected hard foam that has turned to dust everywhere it was used on the car, and Id like to replace mine.

    I did one of them when I had the rear quarter panel off with some of that square self-adhesive weatherstripping foam, but Im really not happy with how it looks; the foam has big pores and is a light grey that looks obvious against the black pontoon.

    What is everyone else using for these seals?

    These are the vents I mean, that lead to the engine intake/power antenna/ areas inside the rear pontoons

    You can use square weatherstripping or you can take the old seals, cut them open, clean out what's left of the old foam, make new foam "doughnuts" and then glue the covering back together. The tough part is if you don't take everything all apart you must cut the seal so you can remove it and reinstall it around the duct. Just hide the seam around the back where no one can see it.

    Hmm, those shank washers are an interesting idea. They look a little short for my taste but are a decent option.

    The deteriorated original seals are long gone so rebuilding them isnt an option. And as I said, I dont like the look of the weatherstripping which I have already installed.

    I replaced the rear speakers with new elliptical speakers. Each speaker had a rubber ring covering the magnet and this had to be removed to enable the new speakers to fit the rear interior panels.
    These rubber rings/doughnuts were perfect for this.

    Why not buy a small sheet of self adhesive closed cell foam and cut your own rings.

    You could perhaps use a heated cookie cutter ring of the right diameter to cut/melt the foam to the correct size/shape.
