Re: '67 12 bolt gear ratio
If you don't want to pull the diff cover you can use these two calculators.
Get you tire size https://tiresize.com/calculator/ To find you gear ratio take the truck out and use your GPS to get an accurate MPH and a tach to get your RPM in top gear at like 70mph. Then put all that info onto https://www.summitracing.com/popup/c...iAAEgIFzvD_BwE
