With those numbers (looks a lot worse in the picture) seems like bent frame is not the issue. Normally,you can't put that much positive caster in the thing, so wheel alignment is not the issue either. A lot of people run a 26.1" tire too (and up to 245 width), so that shouldn't affect it. So with that you should not be having these issues. But you do, so something else must be wrong.

My bet is the subframe is sitting too far back on the body. If you do a search you can find directions on how get it properly lined up. I'd do that since it will have an effect on handling, will limit how much positive cster you can put in the alignment, affect clearance to the distributer (probably not critical unless you go HEI), and looks a little goofy. I know you just want to get it on the road, but it's a nice car, don't band-aid fix it.
