12 bolt Yokes Slinger

[68camaroz28]

The yoke attached to the rear end has a large cup style washer that we always called a "slinger", and assume it got called that since it slings the crap away from getting in the seal area. I would like to find a slinger that is in better condition than the donor I have currently as that one has pits. The orig. owner changed rear gears back and forth (put the originals back in before selling) and the slinger has been gone since 1974 or before, hence the need for a donor.  And if forced to keep what I have and move forward I'm not sure what finish they came from the factory with.
1. Can anyone help me with obtaining a nice used or new slinger?
2. What type of finish did that slinger come with new? Natural, phosphate, etc.?
Appreciate any help and thank you!

Question# 2,
All natural, but do not know how much black over spray, if any, is supposed to be on the slinger. If a can was used on the yoke then there could be light over spray on the back of the slinger as well as the front of the cast 3rd member.
John Z may be able to shed so light as to how the yoke was protected during the spray process, but I think the complete housing was  painted black at the supplier.

Bob, per JohnZ, "a cardboard cap was placed over the yoke when the axle assembly (including the brake drums, parking brake cables and wheel cylinders) was painted at Detroit Gear & Axle." Probably some paint was on the slinger but maybe very little so good question. I was assuming it was very little if any paint and if the slinger was phosphated or just a steel stamping. Your question is important to know the best process to follow for restoration.

I do not have a 3878972  3-27/32" dia. yoke that you need, but I have a 3879208 4-5/16" dia. yoke for my 67 and it has no plating of any kind, just like the drive shaft. Forged casting and steel stamping. Does have a green paint dab on one of the ears.
I would think, with the cap in place very little paint would be ion the end of the 3rd member under the slinger. Reason, probably re-used the caps.
When I paint the complete housing, I will tape off the yoke @ the outer slinger, stand back about 2 to 3 feet and let her rip.
