You can tap on the hex end with a dead blow hammer (not steel!!!), but be sure not to mar up the outside of the bar once it tapers down. You may need to play with how far down the LCA is hanging to get it lined up just right. Did you grease the hex end of the bar and/or the socket in the LCA? If not, that'll help. Are the bars or LCA's painted or powder coated? If they are you may have to remove some of the paint in order to get the bar to slide in.
As far as loading them, once they're in far enough to get the clips in you just need to hook up the spindles and turn the adjusters. I wouldn't go crazy while it was still on the rotisserie, just tighten the adjusters until you start to feel some tension. If you didn't make note of how many turns you were in before you pulled the car apart, or you've upgraded the diameter of the bars or gotten a bigger engine you'll have to do your fine tuning once you can get it on the ground. At that point you'll have to jack up the front (so the adjusters don't strip out and unload the torsion bars while you're under the car
) and make adjustments to the ride height. Be sure the roll the car in between adjustments ( a drive around the block is best), bouncing up and down on the bumper is NOT enough to settle the suspension and check the ride height.
