Axels Are Out, Posi Is In

After jacking up the back-end and putting the car on car stands, removing the brake drums and the four bolts holding on the backing plate, I pulled the axles.  The driver's side required only a couple of slight taps outward--which is fortunate because there is little clearance to tap outward..  The passenger side required the use of a sliding hammer to break the 31 spline axle loose from the differential.  Came out pretty slick.  I took the axles to a friend to remove the old bearings, and press on new ones. 

With the Axles out, I removed the open 3.08 diff..  It looked like new inside.  These Pontiac rear-ends are heavy.  One can see why they were so popular for racing and dragging.    They are super simple to swap out, once you know what you're doing.

I cleaned up all of the surfaces where future gaskets (supplied by Fabcraft) will go.  I hoisted the rebuilt Posi 3.64 up, with new gasket and RTV already in place--almost dropping it--and got it installed.  A true sense of accomplishment.  Next step: replace the axle bearing seals, get the axles back and popped in, and reinstall the brakes still assembled on the backing plates.
