Glad all's well that ends well.
Terratup, this may sound overly simple, but are you checking your measurements on level ground? That could make a difference.
When you crank the torsion bars, the differences in the gap at the bumpstop vs. any differences in height are not equal, meaning that if you gain a 1/4 inch in ride height, you don't decrease the gap at the bumpstop by that amount.
Perhaps the best way if heard the relationship explained was on this site -- and I wish I remembered who it was to give them credit -- but visualize one of those gardening/branch trimming tools that have 3-foot handles but the pivot point of the tool is down next to the blades, which are only like an inch or two long. With the handles all of the way open, like when you're cutting a branch, the gap at the ends of the handles is several feet apart while the blades are an inch apart. If you close the handles half way, you've moved them like a foot while the distance between the blades also decreased but in a much much smaller proportion than the other side. It's kind of like that when you crank the torsion bars, when you crank them up, the gap at the bumpstop decreases in tiny increments. Ultimately, though, you are lifting the truck at the expense of down travel and too little clearance can cause problems.
So long story short, by evening out your measurement, the gap at your bumpstop might not diminish all that much or, if you're measuring using the eyeball method, it might not appear substantially different.
Hope the long post made some sense, my brain's a little fried at work right now.
Whomever posted that earlier analogy from the way back, thanks again.
