Overdrive will definitely be in my future. For now, I'll likely swap between the 4.10 and 3.23 centersections I have for race days and longer distance cruises.
I did this years ago in my 71 challenger, to make it easier on your self, add some extra length to the rear brake lines, and put a drain plug in the rear end.
This will allow you to drain the fluid easy, and pull the axles out far enough without having to bleed the brakes.
I could change a rear gears in that car on jack stands in under 30 minutes using hand tools. But I was also alot younger.
