Dimensions???
I may have to pull my patterns and such out to check. It depends on a few things. (1) Do you plan to cut/remove the pad from the back wall? (2) Are you planning to remove/fill the vents on the back wall? (3) Are you planning on cutting the jack bracket from the floor and relocating your jack? If this is the case, I may be able to help you shortly. I needed this info when I was in Iraq, as I planned a box when I returned. Unfortunately, I was unable to get accurate measurements until after I returned, so a LOT of planning time was lost.
