Lower control arm adjustment

I had 2 inch ranchero coil overs put on my 96 the other day just to find out i had a boken leaf on the drivers side. This made the drivers side sag and i thought it would level out once i put in a new leaf. I just did totally new leaf packs and it is still sagging on the drivers side. Also, as i was installing a new steering rack (its been a fun week) i noticed the front control arm bolt was extremely loose. I did not know this adjusted the caster so i went to tighten it, i did not bend the tabs but it made the truck sag even more. is there anyone who knows how to properly adjust these. It makes sense because the i took it for an alignment after the coil overs firestone said they could not align it right. Shouldn't they or the shop that installed the coils have caught the loose bolt? THANKS

(My hope was that i could get it close the adjustment on the other side enough to take it in for an alignment)

 

pics of your saggy taco? haha

 

no i just dropped it off at the shop for the alignment.
