This is the new company that Sportsmobile West used to be. Last I checked they do not have a working web page, but you might be able to call them? They used to stock and sell the bras. You could also try the other SMB sites. As far as the bra itself, be advised they tend to damage the underlying factory paint over time (maybe caused by excessive heat?)...
If I had an unblemished hood, I wouldn't use mine. However, I purchased my van with the bra included and some paint damage was already present, so I have nothing to loose.
