Very cool that this is an ATR setup. I thought the previous owner put it together. I am interested to see how my car launches with my new hrparts swaybar, uppers, and lowers compared to this ATR torque arm setup with stock uppers/lowers.
No idea what it originally sold for, it was on my car when I purchased it in 1998. They are long since out of production. I had another thread about this setup here a few months ago and no one had seen one pop up for sale.....seems like maybe they didn't catch on....so likely not too many out there.
