I've placed a wanted ad for a 100% carbon 430 mast top but just asking here if anyone has one they want to sell. It's pretty hard matching the diameter even with other North stuff so looking for a Platinum top. Mines from 2010 so done some miles. It measures 36.4mm inside dimension.
I've got a Platinum 400 sdm mast for sale ($350), not sure what the top section length is but will check later 
Sorry I don't have a 430 top but have the top piece of a 2019 Platinum Aero 3.0 400 RDM if anyones looking (unfortunately I broke the bottom piece 
).
(Cue: Ezzy sailors reminding everyone that you can by Ezzy mast pieces separately 
)
