Yes, that's how it looks to me. I don't immediately see any way to change it - tinkering about with removing weight behind the firewall isn't going to make much difference - you really need to move the rear wheels and that becomes a real nightmare, plus it looks wrong.
I think you have to just suck it and see. Maybe rip out all you can and then do a test weigh to see how far out it is - no point waiting till it's finished to find you can't tow it.
