hey D.Hearne. I think its a wide ratio..if so the I will be happy with 3.50's where on the case do i look ? I going to do the refresh kit in it as well.D.Hearne said:One more variable you need to consider-- what Toploader? Wide or Close ratio? With a wide ratio, 3.50's are perfect for street and freeway. With a close ratio and a less than torquey motor, you'll need to step up to 3.70-3.90's, to compensate for the close ratio's taller 1st gear.
