8 3/4 Rear Differential - Correct Colours

[Shakey]

I am completely rebuilding my rear differential housing and I am interested in knowing the correct colours / finishes for the items that are included in the assembly.

After searching I have learned that the backing plates are supposed to be zinc phosphate, the drums could be primer red or black and the shock mounting pads are gloss black.

Can anyone tell me what the correct colours are for the items depicted in the attached photos?

as far as I know the carrier is natural cast iron
the sunbber I believe is black

[hemihead]

The yoke should be natural also

I was always led to believe that the backing plates were semi gloss black and not zinc.

There was a link on here to 69HEMI's site that had an article scanned from a magazine a few years back that stated they were zinc phosphate.

I was going by that.  I think zinc phosphate is like charcoal gray but I am not 100% sure.

Some third member housings were finished in red oxide.

Looking at your case you can see traces of orange paint.

Not too sure about 69 & older but 70 & newer had a paint coding system for gear ratios, sure-grip & size of yoke/u-joint

On my case I painted it cast iron color.

On the bottom I painted 3 white daubs & 1 orange daub of paint.

This denotes a 3.55:1 ratio with the large 7290 joint and a Sure-Grip

There is to be an orange daub of paint on the filler plug as well to show it is Sure-Grip equipped.

The backing plates I have seen either semi gloss black or the black zinc phosphate.
The housing itself I have seen semi gloss (30%) black
