Would anyone happen to have a picture of what my differential should look like. I know housing is red and dif is semi gloss black but I’d like to see snubber bracket ext. and possibly paint marks from factory. Thanks.

Sure you meant to write that in reverse


Don't typically keep many pictures of restored cars since you often have to crop out incorrect details or photoshop them and in general they aren't good for documentation but have a few. And if we just copy, we don't didcover anything new.

Since you didn't mention it the third member would have a number of fresh machined surfaces. The sunken ring on the face of the pinion retainer as well as these bottom ones. Fill plug would be unpainted.



Housing would be painted semi-gloss black except for the surface where the gasket for the third member would sit and the backing plate gaskets would touch also.



Snubber bracket would be all bare stamped steel with some areas of the surface slightly brighter from the stretching and forming process

Same snubber bracket - different application  (non-N) so pinion and case details will be different from your car.

Thanks so much. How would I find out what markings the factory added ?  May car from San Jose. Thanks.

Also would the 4 stud bolts that hold the break housing in place be left un painted as well?

Guess you may be asking about the bolts that attach the backing plates to the rearend housing (as well the axle retainers)- the two were not bolted together when either part was painted and they were painted at two different places and non of these parts had any other part or hardware installed/attached.  Backing plates at Kelsey or Bendix and the housing likely at the Sterling Ford plant  Don't think it was outsourced

Hi Guys. How can I verify what paint markings would be on my dif ?

Hi Guys. How can I verify what paint markings would be on my dif ?

Only way to verify would be to have found and documented what was originally on the 3rd member. Each would be different - slightly or more since a number of workers would have handled it  Only way to ensure even the basic typical markings is to look at allot of examples from the same time period and plant.

Have to ask - standard practice - is everything else on the car 100% factory?  Paint marks, if showing, typically don't make up for short comings or personal choices elsewhere on the car.

Thanks Jeff. The car was restored once so all the markings were painted over or sanded off. I think being a 428cj 4 speed red on red car it’s worth trying to get it as correct as I can.

I’m trying to post pics but it won’t allow me for some reason. The page keeps failing.

Not sure what isn't working for you. There are a couple of threads on posting pictures or even using your gallery for that purpose. Can just send them to the email I sent you in the PM

Here is a pic of the diff

For you and others looking at the thread the finish on the 3rd members originally was not a primer (flat finish) but as a red oxide dealer do normally a little darker and with a slight or more shine to the finish.

Also there would have been no sealant visible or used on the third member gasket.

There has been discussions in other threads related to if the upper studs received the cooper washers or not - Just a heads up

Rear end ID tag would have been bare metal. Looks like your still has some old black paint or something else on the surface.
