To rebuild the distributor on a 1987 Chevy 305, start by removing the distributor from the engine. Once removed, take off the cap and rotor, and inspect or replace the ignition module and pickup coil if necessary. Clean all components, replace worn parts, and reassemble the distributor. Finally, reinstall the distributor, ensuring it is properly timed with the engine.
I believe that one sits under the coil packs.
