Razz, not sure what type of trunk opening system you have, but if you have the torsion rods like the '00 cavy does, be sure you make the box a little shorter and a little narrower than you're thinking. I was able to fit a 35" wide-by-20" deep-by-17" high box in a '00 cavy but it took some cutting of the body behind the seat, removal of the torsion bars (so the trunk became fully manual, had to hold it open), and repositioning of the trunk brackets. *this box was for a different, much larger sub* You shouldn't need a box even half as large, just some dimensional guidelines to go by.
