issue with AMD Demon floor pan..please help newbie

here is a few pics of the floor laying against the top of the transmission hump without the floor being clamped into place at the firewall, as you can see the gap at the firewall :S also the gap on the sides of the trans hump, if i were able to push it in i would assume it wouldnt line up at the front at the firewall.

I would definitely be bolting that crossmember back in ... see if that helps some.
But even if it stays the same leave it in when you're welding that floor pan in.
Also check all your door gaps you might need to backup a few steps and re brace before you weld it in if AMD is correct on the firewall moving forward.
Lets face it it wont be ready tomorrow night , so take your time. " Haste makes waste "
