DUH!?!?!?!?

A quick search pulled up this... http://shortorderproducts.com/RibType_Pages/rt-ab_RibType_FONTS/rt_ab_RibType_Fonts.html

FWIW I bought three sets from my local print shop back in the 90's, All three sets together were around fifty bucks... I've used them on six cars & I've loaned them to a few friends...

Just dropped in and you're right it's a 073... ...No wonder I could'nt find the code when I did a quick search the other day...

I thought it might have been my camera there for a bit..

We will be offering the original type stamps by the end of the summer. They will incorporate the exact font as the ones used by the factory. Here is a sample of what was in my Challenger and the stamps I made that matched exactly what was originally there.

Any thoughts on what these codes mean on mine?

On the other side of your third member, under the protruding lip, is there another white stamping of some kind? If not, that marking may be some type of date code for your particular unit. Keep in mind that there were a couple of variations and changes for the way the date was stamped throughout the year.

Here is the other side..and thanks for the info...interesting to know !

Your casting is completely different than the one in my car. I have seen the variations but never gave it too much thought. That is the date stamped on the side by the filler hole because that casting did not allow enough room to be stamped on the reinforcing rib underside. Look at my example and you can see the difference. My date of 12/6 is stamped on the underside of the casted rib. I will post 3 different rear end housings (as soon as I take the pictures) to show the contrasting styles that were used. Thanks!

You are correct. I documented a Challenger T/A that had another yellow stamping on the direct opposite adjacent side of the front date stamping. I would like to find someone who worked at the facility and was part of this stamping procedure. They could help take the guess work out of what we are trying to uncover.

On OZHEMI`s photo would`nt the date code be the 2189 under the part number?

Would that go along with this code?

Another good thread on this subject from the past:

Can you guys indicate a font which is a good approximation of the 3 digit part number on the axle tube?

11-10 I understand the X I`m not sure the date on the gears is what?

When are you thinking you may have your stamps ready for resale?

The stampings were done to make "sense" for whatever plant or employees needed to understand the rear end breakdown. I am not sure what all of the variations and colors of markings meant. Having the original samples certainly makes it easier to eliminate the guess work when trying to replace them.
I can have stamps made up at anytime. I do not have a set program or pricing as of yet. We just finished the different fonts, so this project is still in the beginning stages.
