Opti

Replace the whole thing.
You can't just replace the cap & Rotor.
The units go bad at 60,000 on the average.
Spend the extra money dude

I'm thinking of having my car dyno'd soon just to see where it's at. The idle is not too bad. Every now and then I barely hear a strange noise at idle but that could easily be something else with some of the mods I've done.

Actually you can just buy a cap and rotor and replace those. That's what the previous owner did on my 93.

With over 100k, just replace the whole unit.

I highly recommend the MSD Opti. Mine works like a champ, and it got me about .05 - .10 in the 1/4 mile improvement.

The cap and rotor cost almost as much as the whole thing and if you have to take everything off the front of the engine you might as well replace it all with that many miles.
