I don't remember the MP number but just go to the Mancini website and look under ignitions. The MP version is $350 while the MSD part number is $560.

While we're on the subject, here is a coil bracket that I made for the HVC style coils. This bracket bolts to the end of the cylinder head. I also did a bracket for the Pro Power coil but I'll have to dig around for that picture.
