How do I ID a 4 speed, overdrive or not?

Nice, looks like 3.91's should fit the bill then. I'm gonna try to find a used set to run for now and I know I wouldnt find anyused 3.73's for an 8 1/4. Sounds like a nice combo you have there, nice cruising car that will boogy if you want it too, nice. Thanks for the info
