Removing speedometer without removing the instr board?

I need to get the speedometer to a workshop but dont feel like removing the complete board (I alteadu have the board down on a 140 dhc).
This time it’s a 120 FHC. Thought I might get the securing screws, lamps and speedo cable off from underneath, with just the cover plate down…
Wishful thinking?

Yes, theoretically possible, there are four clamps.
