ok kool
well if i remember ur width is 38wide(in between wheel wells)
as far as depth not sure how deep u want to go but i think 18inches is a good starting point...and height not sure but i wil try and keep it below the window line...so im going to say 15
38w x 15h x 18 d
as far as port im thinkin 1 slot port going across the bottom...but the catch is the lenght is going to be slanted
heres wat im thinking..if some 1 can sketch this up that would be great

the numbers on the inside are the internal measurements
80
