Hey,

I'm getting lost with those gears PN...

At first my speedo needle was shaking, so I thought a new gear would help,
so I ordered the stock (purple) one, but then I understood that a new speedo cable will solve the problem - ok I ordered one (didn't get it yet).

On top of that my speedo is showing lower speed then real, ex:
speedo 100km/h
gps 112km/h

After digging around about this I understood that a 21 tooth gear would help - I ordered one, the one I got had the tooth aligned to the opposite side compered to the stock purple one...

My question is:
- What is the right PN for a 21 tooth gear ?
- 21 will fix my speedo showing lower speed ?

Thanks !

It is a 97 turbo miata with 6spd and NB LSD
