Weird question: I was looking at cap and rotor kits for the opti, and I'm curious about something on the MSDs. I noticed when looking at them that there seems to be either a red one with black lettering, and a black one with red lettering. I assume the design simply changed at some point, can anyone tell me what the current units look like? I'm debating on pulling off the opti on the Vette that's been beating me to death on why it won't start and trying a fresh cap and rotor, inspect the internals, and I'd wouldn't mind having the MSD for cosmetic reasons. Anyone use one recently? It seems they've been having quality issues with even those. I thought MSD problems were limited to poor quality optical sensors and poor assembly, but I've seen a few people complain about just the cap and rotor themselves in recent years.
