I've found PB blaster to be far superior to Liquid Wrench for loosening stuck nuts. WD-40 is practically useless in comparison.
Those nuts are supposed to be brass, by the way. Brass doesn't get stuck. You can get the correct brass nuts from any of the usual suspects.
Also, try some heat from a propane torch to get those nuts off. But use the PB blaster first. You can get a plumbing torch from the hardware store for 20 bucks.
