Photos 889 -891 - Drivers spring installed.  Ignore the finger prints from the gloves.  You will also note off to the side you will see I also installed new (actually used but still flexable vs the originals had dry-rotted) rocker "drain flappers" (technical term)

Photo 895 - After and the springs are wiped down and a wrap until I get the diff installed and suspension loaded before I tighten the bushings.

These photos are of the initial teardown.  As you can see the 40 plus year old gear oil had failed.  Current plan is to reuse the carrier which I believe might be the original to the car (can not verify) but since the speedo cable was apparently routed the non muncie way I can route the cable (which I still have CA) and assuming the car had a speedo adapter it would reach and have no issues.  You can also see a wear pattern where the cable rubbed the firewall.

One thing I failed to mention previously was that I will be swapping gear ratios to a 4.56 as I plan to run a 28" tire and I will need this little small block in the rpms fairly quick or at least that is the intent.  Of course new bearings, seals, brakes and an overall clean up will be the following steps to come.

Photo 904 - Pumpkin wiped out, caps, shims, pin and bolt are clean.  I will be using an aluminum diff cover I snagged from a buddy which I shared in a previous post.

Up next was the removal of the pinion nut & pinion as well as removing the carrier & axle bearings and said seals.  Also adding the axle stamping & casting date.

Photos 908 - 910 - Old axle bearings removed and new bearings and seals installed.  Also added a shot of the inside of the tubes.  Very clean once the grease was removed.

Last for today was the removal of the pinion races (Not pictured) and the "new" gear set.  GM dated 10/65 & 11/65 ring & pinion.  Hopefully up next will be the "derustification" of the housing and the installation of the carrier bearings and start to setup the pinion depth etc.  Once that is finished I will set up the backlash and get a wear pattern.

Drug out the ole evaporust and setup a quickie bath for the diff.  Slow going process at this point before I get back into reassembly.

I also starting the cleaning and preserving process of other diff components.

Here is a photo from above for comparison on the brake parts.
