[Rear end gear ratio]

Present ratio a 3.33 and engine is 3500 rpm at 60 really roaring. Can’t keep up With modern traffic. IS says I need higher ratio like a 3.03 but manual says stock was a3.34: tranny is auto   3 speed. None of the parts dealers have any gears available. If I️ can find suitable ring and pinion will have work done by tranny shop as I️ don’t have expertise .
