does anyone have the dimensions of a trunk frmo a 1991 318i, want to build a box to raise the trunk up about 2.5 inches so that i can bury my amp into the floor and not have it get damaged while still saving space, i just dont want to go outside and measure my trunk because it is to cold and i have to much crap in there right now, so if anyone has a picture of the layout with some dimensions that would be great. thanks.
