Convert to SC 1000 to Vessel View?

[Hossmoss]

Would like to change out my clouded up sc1000 gauge set for the vessel view. I am running twin 225 optis serial #s OT 749048 & OT 700625. The current gauges have blue backs, 1 speedo and 2 tachs connected to a 6-way smartcraft junction box.

What vessel view parts should I need to make the changeover? Just the display? or something else, too?
