DAWG,
This probably wont be any help,but I found this link for a fiberglass
"air box" from unlimited products.part #CA-141 or #CA-142 I know
there not aluminum..but could be a nice base for making a nice fitting
aluminum one..or a lightweight one with there version.Just a thought.
Here is there link..
