Ride Quality Suspension Upgrade - $3k budget

[cjohnson6772]

Working on a 72 C10 and need advise. I am primarily looking for ride quality with some handling improvement being secondary. I would like to spend $3k or less to help fund other project. If costs exceed $3k I will probably just buy the full QA1 or Ridetech coilover set up.

Current state:
Stock suspension
Stock front sway bar
Riveted in factory ball joints
Worn front trailing arm bushings
Worn panhard bar bushing
10 year old Monroe Gas Magnum shocks

Desired state:
Approximately 3/5 or 4/6 drop
Planning CPP modular spindles

The rest is up in the air. I would prefer a new setup of front arms to avoid having to deal with the ball joints and to improve caster.

I have consider NoLimit rear panhard and rear shock relocation brackets. I just don't want to sink a lot of money into a sub par set up if I really NEED coilovers and a $5k suspension to be happy with ride.

I guess what I am asking, is for advise on the most cost effective and highest impact suspension upgrades.
