Fbody struts for an 02

I’m in the middle of doing a spring swap. I removed the front strut assembly and found that the top threads / nut are SUPER badly corroded, to the point that there is no way I will be able to reuse them.

As of now, I’m looking for anything - new, used, aftermarket, whatever, just need something asap so I can get it out of the garage.

Do you think this is something auto parts stores would have in stock? Looking online, it seems like they’re a special order…I will have to call in the morning.
