I just ordered 4.10's and I am in a similar situation - I have an 8 tooth drive gear and 19 tooth driven gear in my T5 with 3.08 gears. The 23 tooth driven gear will still put me about 15% off. I sent an e-mail to a Speedometer shop that builds mechanical correction boxes. They quoted me $60 for a new speedometer cable, and $65 for the correction box. I guess you can't just splice your current cable?

The other option is to replace the Drive gear with a 6 tooth gear, and keep the 19 tooth drive gear. That would put me very close with the 4.10's, but apparently changing this Drive gear (at the end of the tailshaft) is a PITA.

So, no easy (or cheap) answers... if anyone can say definitvely the best way to go...please let us know.
