1969 Dart Street/Strip (Re)Build

Well I got one tub mostly welded up. I went to the front of the tub to finish welding the inside where the tub meets the floor pan. Apparently I did not look at this area very well when I tacked it up. The tub sticks out WAY further forward than the other original side! Fearing the worst I throw the back seat in and sure enough, I've mislocated the tub so much that the seat frame hits it and is holding the seat out! I can't believe I've done this. I'm usually so anal about making things look right and fit right. This is a nightmare for me and I'm almost too ashamed to even post this, but I'm hoping at least one other person here has done the same thing. Anyone else pull one of these bonehead moves? I'm thinking I may be able to bend the seat frame in enough to make it work. I'll have to look at it more tomorrow. What's weird is that it looks right at the back, but it's definitely off at the front. Thoughts?
