front end sits too low

The torsion bars were installed with the adjuster bolts screwed in to far.
This is why you have run out of adjustment room on the bolts.

Put the car on stands,loosen torsion bar, bolts, back torsion bars out from lower control arm,loosen the adjuster bolts almost all the way out,reinstall torsion bars,tighten the adjuster bolts. Done
Now you should have all the adjustment necessary.

I've done that before, it didn't make a difference for some reason. It'd have some ride height for a while and over a week or so it'd return to the same height it had before. Adjust and repeat until the adjuster won't go any further.

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.

What pics do you guys want to see? I'll post them shortly.
