Your second picture looks like your measurement is to the cab support BELOW the floor proper. Measure to the bottom of the floor itself, although that will only get you 1/16" more without adding shims.
On the rear, is it possible that the cab shackles are too long? Are they originals? Here's a picture of mine wen removed, although I can't measure them right now, yours look a little skinnier, but maybe that's just the way the picture makes them look.
