Review on A-Team Performance Optispark Spline Drive Distributor 8 Cylinders for 1995-97 GMC Chevrolet Chevy Corvette Camaro LT1 LT4 V8 5.7L - Black Cap by Joseph Meola

Replaced in my 1995 Corvette. Before assembly, loosen and tighten the screws. This prevents the screws from vibrating. There should be two on the rotor and two holding the rotor wheel. Remove the cover from the Optispark and draw a line where it matches the engine. Engine key hole. There are three holes, but only one is correct. If you stick it in other holes, your time is up and you have to rip everything back to fix it. Also if you have trouble turning off your harmonic balancer. Just loosen three screws and hit the engine without starting it and it will fall down. The balancer only returns in one direction. Screw holes are misaligned. Number the spark plug order. Remove the throttle body and choke to the air cleaner and all associated fittings, then the water pump comes out easily. Also, first connect the spark plug wires to the Octispark on the driver's side before installing the Optispark. line below too. I smeared the edges of the Optispark with high temp silicone to keep water out. The snake belt must also be removed. Hope this helps someone.
