The bottom prism won't move? Or does it move but nothing seems to line up? Do you see two images, or just one? Perhaps you moved the lateral so far that it doesn't line up at all? Everything is fixable except for stripping the left-handed scew. Don't freak out, I've thrown my kalart completely out and adjusted it for a particular lens again. It's not hard, just takes time and patience.
Just tell us which screws you adjusted and maybe a little more, you know?
As for NYC, sorry i'm real far. There is enough out there online and on this forum and graflex.com to DIY though.
ps- do you have a laser-point pen? it makes adjusting/aligning these things A LOT EASIER.
