1995 LT1 Easy Optispark installation

My new distributor came with no instructions. I messed with it for 30 minutes, watched some BS You-tubers that claimed to "Install the Optispark," but they didn't explain how they did it. (They're all more interested in being on camera.) Then, I opened it up and turned the rotor, and it lined up easily. You'll need a 4mm torque bit to open it.
