I have the wrong speedo gears in my trans. My rear gears are 3.73, Do i need to change the metal gear on the input shaft or just the plastic one on the cable???

Not near enough info to answer that one.
Might just need the driven gear but depends on what drive gear is in there now.
Have some info:
Still not enough info.
Check the links I posted for what you need to input to find the correct gear/s.
Sounds like you need to change both gears to get the ratio you need.
Alternative is to have a speedometer shop build you a ratio adapter.
This way you don't need to pull the tail housing to change the drive gear.
