Yeah. My AC guy said there was only one place he could get a copper one, for a car he was working on, and it was US made, very expensive, and complete dogshit.
I think the one I replaced in the Blk/Gry Ty I sold was Spectra from SummitRacing. I remember it was difficult to get the silver straps over the end tanks because they were a bit bigger than original. Did you run into that? I think I had to straighten the hose side strap to get it to line up w the bottom screw.
I'm gonna order one from NAPA because that's my best option for now.
