Topic: 1968 S code diff casing finish.

Well I jumped the gun and have already painted the daubs before I digested the last post. I couldn't find any stainless coloured paint locally, so I used the VHT cast iron. Its lighter (more steel like) than my iPhone photos show, and was an exact match for the fresh cast iron on the Currie Ford 1330 long yoke, so not too bad.

In any case I am generally pleased with the rear axle. :-)

I found the remains of a yellow daub by the filler plug, under a layer of paint so I noted that, (complete with run) and replicated same on the carrier.
The yoke is as mentioned, with a yellow driveshaft clocking blob and a spray of Ford blue across the lower yoke and dust shield.
I didn't notice any blue remnants on the pinion support so I just allowed the barest of touches there.

In any case I think this will do unless I find some further markings info re inspector crayon scrawls etc.
Thanks for all the assistance.

The center section/ 3rd member/ pig was originally painted prior to machining inside and out with a red oxide colored epoxy that was slightly glossy (not flat like open primer)

There will be natural machined metal on the pinion retainer and three sections on the bottom/sides of the main case





Plant code?  Suggest you post what you have and what is illegible

I see Model code - Ratio - Date - Assembly code



Will send you a pm rather than post details here since they are so often borrowed or migrate to other years and models if posted   

I was looking to determine what machining surfaces there were on the differential pumpkin.  I found this information but not sure if it applies to my car.

it should apply as the axle assembly's were made at the sterling plant and then shipped to the different assembly plants.

It is my understanding that the axle assembly included the housing , brake backing plates ,axles and center section . It was shipped as a complete unit to the assembly plant.

Thank you.  In the picture I reposted, there are three yellow arrows. I'm assuming the middle bottom one points to the pinion retainer.  The other 2 are noticeable and on the body.  The post says there are 3 areas machined on the body.  Where is the other one?

One other thing.  It appears the pinion  retainer plate is painted red around the sides and just the flat surface is machined.  It's that also correct?

Correct on this application. On some rearend pinion retainers the surface is not flat and machined all the way around - just pads

Just wanted to add to this thread that I discovered a yellow dab on my pinion yoke as pictured.
