Is my speedo and odo off with 31's?

[TOY350]

It is calibrated for a FJ60 that has switched to 4.11's and 33's. Stock FJ62's are 4.11 so the stock ratios will be different and I don't think it will be correct on a 62.

I will repost under the for sale forum if MO60 or Overlord don't get back to me.

GPS works best to figure out the error. I use the GPS as a speedo more than anything else.
