The fiberglass enclosure I created to fit into my spare has a mounting depth of 6.65" - a VERY TIGHT FIT for sure. I figured with a small circle spacer I could add another 1/4 to 1/2 inch to that. It would stick out, but not that much - again, just by the amount of the spacer I'd use.

AlaskaVX - by any chance is your friends 12.1 installed in a VX?

(p.s. - I seem to have started this thread in the wrong area 'meetings'. anybody know how to recategorize this thread?)
