To drop the front suspension, dropped spindles, new steering arms, and coil springs were sourced from Jamco, along with new kingpins, thrust bearings, and bushes. There's not much point trying to reuse the old ones if everything else is being replaced. The dropped Chevy spindle (actually a raised upright!) effectively raises the kingpin boss, in turn lowering the car. We ran a pair of these on our Project '49 Chevy for years before installing a Mustang II-based IFS, and they worked just fine.
