I would use stiffer, shorter springs and a tall lower ball joint to lower it in front vs spindles (and use stock S10 blazer spindles as a basis for a big brake conversion). If you use drop spindles in front, definitely up the spring rate or the tires will hit the inner fenders much more than the same height with just lower/stiffer springs.
Shorter, stiffer springs with good shocks and ZQ8 bumpstops (vs. the factory hard urethane) actually rides pretty good.
When you lower the car, the fenderwells will need some work, but based on all of the cool subtle body mods you have already done to the car, it shouldn't be a big deal.
