So on my awesome 99 Astral that the previous owners (Bimati and grantCO) took such great care of, I am trying to take care of a few little issue before tackling bigger stuff (like...has the timing belt been changed ever? does it need to be now?).

I noticed one of my rear license plate lights is burned out, but the screws holding the lenses on both of them are rusted to hell, and all the WD40, elbow grease, and careful non-stripping force I can apply will not budge them.

They are too recessed to get vice grips on...I could try to dremel flats on but it's a very hard location to get to with the dremel, and I don't want to crack the lenses (I think they are glass).

Any other ideas I can try? I have the replacement bulbs. I need to get a torx wrench big enough for the cladding (my largest is a T20) if that enables me to get to the back side of the screws.
