question for those with shaved lower body seams

Yeah, I looked at the contour with a flat edge, and I'd have to make the patch panel extend all the way to the cab corner and then wrap around...I simply don't have the tools to make a patch panel of that nature...so welding and some body work is all I can do, it'll still be on two planes, but oh well.

your truck must be different then mine, on my 96 i could just weld it up, sounds like you want to make a whole new rocker panel for the ext cab part.

Nah, not a whole new panel, but where the two body panels meet, they aren't even. I can put a straight edge (framing square) so that it rests on the rocker panel, and the small section under the door is lower then the straight edge by about 3/8".

Sorta looks like this when viewed from above:
