need help with speedo recalibrating

[SNKBYT]

I am looking for the dip switch settings for recalibrating to a 3.45 rear end. The dip switch was installed in 1997. Does any have the sequence for this ratio? Thanks Tim

SNKBYT, check out this link to SPECMO's website. SPECMO they have a link on there for dipswitch settings. I believe I have a 3.45 axle ratio also and the switch settings were for a ratio of .8929? , the link should be cut and 5, 6, and 7 dip switches should be in the on position. At least that's the way I read this. My SPECMO RB-2120 speedometer recalibrator melted inside the engine compartment from the heat and I replaced it with one from Sean Roe that goes inside the car.
