4.30 gear is 10/35
3.90 gear is 10/31

Interesting, when I asked my local Toyota parts place what teeth I could get, they only said 32, 33 and 34 teeth.

Do you have the part numbers for the 31 and 35 teeth? Do they do a 36 tooth gear?

FYI

4.10 gear is 10/33
3.73 gear is 11/33

You can also use 11/35 for a 3.9 gearset, but it will read 0.5% out compared to 10/31

Oh man, THANK YOU PeeWee. I just swapped for a 3.73 rear end for the turbo but the person I'm swapping with didn't have the right speedo gear. You just made my hunt for the speedo gear much easier (I hope). Assuming that the local Toyota parts guys will know what I'm asking for...

Have just got to love how well the search feature works.
