Thanks.....I had not seen those photos, so I guess I did not dig far enough in the site. I now understand why when I asked Autopower if they make cages for a Crossfire why they were so abrupt with thier "NO". Looks like he did not attach to the bulkhead at all and had a tube just over it. Hmmmm....
That helped a lot!

P.S. You may have just saved me from looking at a Cobalt SS.....
