A Body Disc Brake Swap 101
There is supposed to be a small amount of preload on the torsion bars. Like was stated in that other thread...
Torsion adjust bolts backed out, either end of shock disconnected
( I prefer to remove the lower shock bolt ), and upper arm bump stop removed. Now, with the upper arm in lowest possible position, ( loosen the strut rod bushings if necessary ) adjust finger rotated down against the adjust bolt, install the torsion bars.
put everything back together. You can go ahead and run the adjust bolt up to about centered in the threads. Lower the vehicle to reattach shock bolt and reinstall the upper bump stop.
All this from memory, hope I got it about right.
