Torsion bar install question
What torsion bars do you have?
Installing the bars a hex flat off, with torsion bars that have the factory hex offset, is nearly impossible. It really only comes into play if you have tubular LCA's, which don't hit the K frame so they can hang straight down and allow a different flat to be used (not good!) and with really large torsion bars that have little or no hex offset. The large bars will install with the LCA much closer to its final ride height position, because they don't move nearly as much with the weight of the car.
So, it's really unlikely you're a hex flat off just by pulling down the LCA's a little bit. The other question to look into is, is the LCA lower than it will be with the bump stops installed? If it isn't, that would mean your strut rods will bind the LCA within your range of suspension travel, which is not a good thing.
