Appreciate the comments DUDES..LOL,
here's where I'm at today.
Thankfully my rough measurements I was taking aren't as bad as I first thought.
My buddy and I got the top on the thing today...what a biatch that was.
But we had it hanging from the rafters and backed the truck in under it to measure, and it was seeming like it might be able to not touch the window glass so we lowered it all the way to the bedsides.
The sides of the top are pushed out maybe a 1/4 inch on each side, because the bar hits the window frame, but I think by taking that top spredder bar out, and taking an inch out of it, and pulliing the C pillar bars in it will be good, I'm going to try for about 1/2 inch of clearance between the window frame and the bar.
Fits great at the front, about 1" of clearance around the bar with the top setting in position up there, not a big deal to get the top over the bars up there.
I think with these superduty seats, I have about 2" of clearance between the top and my noggin'
