Looks very ordinary condition and damaged, I doubt it would be worth anyone in the US buying and shipping it, the add says 8/2004 on and it appears that the sticker in the picture of the bar says 08/2002 on, (this was the change of model date) you would reckon the bloke selling it could read the sticker! You should post this in the for sale section, not the TECH section.
AFAIK the bars are made buy whoever gets the contract, ARB did some steel bars for Toyota, and I think TJM did some aluminium bars, I don’t know who does them now. They have to be made to Toyota specifications, which of course also include the design rules of austrailia which I am sure would be different to the US. ARB have to get approval for their bars for the US market IIRC
