Sunfaded models

TandH was able to fit the shell of a 2009 Gordon on a TOMY chassis, so it can be done. In addition to restoring the paint, the plastic itself would be stronger since a faded one eventually becomes brittle; even if you repaint it. Hydrogen peroxide (ironically) also requires sunlight to work, meaning it will actually speed up the cracking/breaking process.

For the triangle screws, a small flat screwdriver/hex key should be able to move them if it fits.

That's really nice to hear! 🙂 The only thing one would lose from using a Mattel shell would be cab stickers, which can be replaced by custom ones, and the unpainted whistle, which if I was in a position, would paint/marker in gold before placing it on the chasis. I guess I would paint the tenders whole, and add stickers for the numbers, unless I'd want to go through the process of resoldering them.
