It doesn't cos you have all the cables and crap coming out all differently, theres quite allof of differences if you have then both infront of you to compare. If your gonna go through the effort of taking it all out wiring it differently then all back together with tue cover you may aswell just chuck it in the boot and not even have it there. Either was too much effort when it was my car so it stayed as is.
Yep exactly that. Even with the whole box it wont fit. Its due to the fuse arrangement on top of the battery. You would need to relocate/remove this in order to fit it.
Probably easier nocking one up out of a piece of stainless
