I agree with Mike here. When using the msd, the points no longer have to break the whole load (around 6 amps I think) and are only used to trigger the msd( around 0.06 amps). Under these conditions the points should last almost indefinately. And if the msd should ever crap out ,and they can do that, trust me, it's very easy to go back to the points to get it home.
