If I replace the plugs, I'm sure that I will probably break one or two. Would you recommend the MSDs as replacements at that time?

If you are stock go with the OEM AC Delco Packard 7mm wires.

However, as an alternative you might consider the Taylor 8mm Spiro Pro custom fit wires. They come in 3 different colors if you want to dress the engine up and cost around $49.99. I was quoted $55.00 for the OEM 7mm wires at an AC Delco authorized parts store.

In my situation my GTP is moderately modded and drag raced so I go with MSD, unequivocally. IMO - plug wires and spark plugs are a matter of personal preference and your circumstances.
