Default TH350 speedo

Need some help if anyone happens to know. I have connected my VSS to the rear ABS sensor for the speedo to work. Does anyone know how to calculate how many teeth are on a stock rear end and how to correct this via tuning? I have seen the formula's for the front abs sensor but not the rear. Thanks for any help and advice.

I have no experience with this but wouldn't it be easier to just buy a pulse generator and plug it in?

Not sure about that one. I have read several threads about the simple solution of wiring the vss to the abs wheel sensor to detect speed. However there is a formula to calibrate the speedo during the tuning process. I have everything done and is in working however the speedo is way off.
