front end sits too low

I've even removed the adjuster bolt, removed the upper ball joint & strut rod and spun the lower control arm down as far as possible to get it in another notch on the bar and then put the adjuster back in and jacked the control arm up to reassemble the front end. That raised the front end, don't know if it would have settled though, that torsion bar broke within a day or two.

That is how it is done, if you didn't do that with your current torsion bars that would explain not having enough adjustment. Back 'em out and put them back in as you explained above. I would say that it was just a fluke that the other bar broke within a couple days.
BTW, this is the "re-clocking" that was brought up in an earlier post.
One other question, when you are doing the adjusting, do you have the front end jacked up with the weight off the LCA?
