I have a rear at home with only one axle.
Its a 3:42 with posi and one 28spline axle. The other one cracked in half.

And.....I have the driverside 28spline axle. Would I need to buy the passenger side replacement. Or could I find another 28spline drivers side. In other words are they interchangeable or designated for a certain side?

and.....I was wondering ....could I use just the housing from an old 26spline rear I have sitting at home for this project?

The 2 axles are the same. So you don't have to specify which side when looking for a replacement. They are the same length, etc.

The housings are the same, as far as the axles are concerned. You would have to use a 28-spline carrier in either housing to use the 28-spline axles.

You may run into other disc/drum compatibility issues with a 26-spline housing if it's a drum one... look them over carefully before spending money. I personally wouldn't put either drum brakes, or the early-style discs (like the 9-bolts and the old 10-bolts have), into a car if I could help it.
