Speedometer Recalibration

[jackbootedthug]

So I finally put in my grand national rear end that had been sitting in the garage for a year and I am very satisfied with the results. Now my speedometer is off though. What do I have to do to fix this?

You will have to get a different gear for your transmission that is compatible for the new gears....That's if you have the stock speedo..... 8)

Thanks for the info. I do have the stock rally gauges and stock transmission. So does anyone know where I would go about getting one these kits to do this.

I got my parts from speedometer world or transmissioncenter.net, they have all the info you will need.
Just Google Gm Speedometer gears.
