Do not waste your time with drop spindles, you don't need them.
Get the offset UCA bushings, and get rid of the stock bumpstops for a set of these
http://www.summitracing.com/parts/ens-9-9132g/overview/. Set your ride height where you want it. How big are your torsion bars? If they're over 1", you only need about an inch of clearance to the short bumpstop. Get an alignment like -.5* camber, +3* to +5* caster, and 1/16" to 1/8" toe in. The stock alignment specs are for bias ply's, not radials, and are horrible for radials.
The short bumpstops are only .375" tall, the stockers are almost 1.5". So you could still lower your car some with the new bumpstops. As long as your torsion bars are over 1" you shouldn't have a problem with hitting the bumpstops.
