HELLO my friends nice to see you agaian at all....
I work in my diferential and I found few numbers.... someone know what´s the meaning or when was it built..???
and what differential carrie is it...? G84 Differential Carrier - 3.31 Ratio G91 Differential Carrier - 3.08 Ratio G92 Rear Axle - 3.08 Ratio G93 Differential Carrier - 3.27 Ratio G94 Rear Axle - 3.31 Ratio G95 Differential Carrier - 3.55 Ratio G96 Rear Axle - 3.55 Ratio G97 Rear Axle - 2.37 Ratio GS1 Rear Axle - 2.73 Ratio GS3 Rear Axle - 3.73 Ratio GS4 Differential Carrier - 3.70 Ratio Positraction GS5 Differential Carrier - 4.11 Ratio GS6 Differential Carrier - 4.56 Ratio Positraction

the numbers you've provided are casting numbers, we need the stamping numbers. They're stamped on the tube that goes from the differential center section to the passenger side backing plate, about 2" (5 cm) from the center section. The stamping faces forward, and you'll likely need to take a wire brush to clean the rust/grime/etc away. They'd be on the left side of the photo that shows the GM2 casting.
See what you can find, and once youy've got it cleaned away, it helps to rub some chalk into the numbers then wipe it off. Tell us the year of the diff, and we should be able to tell you the ratio and whether it's posi or open.

Thanks 67Poncho for letting Micky know where to look. "CP" in the CP 1214K is the meaningful code, and they will let you know the ratio and whether it's open or posi. 1214 is likely Dec 14. What year model car is the diff from??? I can look it up from there. - now that I think about it, my books are packed up as part of a basement reno, but I can get 67rag396 to look it up.

Mar 14, 2009
I think it means CP = 3.36 10 BOLT 12=DEC 14= DAY K = McKinnon (where it was built?) It took a while to load the information...
427carl said
Mar 14, 2009
Looks like "McKinnon" was "rear end" plant in Oshawa Ontario Canada Is your rear a 10 bolt?
Micky said
Mar 15, 2009
was it built on1966...??? beacouse about the day and month ...it`s clear...
427carl said
Mar 15, 2009
your car ia a 67? right? I will look and see if they are the same I think they are.
Micky said
Mar 15, 2009
yes, 427carl... my beaumont is a 67....
I asked beacouse beaumont 1967 was sold betwen 1967 and 1968 until finiched the stock. beacouse beaumont 1967 very few arrived...
and in chile ( I think ) beaumont 1967 arrived in 1966 and 1967 was arrive to sell 1967
what do you think....???
Micky said
Mar 15, 2009
it`s ten bolt
Micky said
Mar 15, 2009
my differential ... is a good differential..?? 3.36 10 bolt...?? is it good...?
what is the carasteristic...?
Micky said
Mar 15, 2009
Yes, my differential have a good traction... when my beaumont 67 has a 6 cylinder
and now I have a v8 350 I dont prove to the differential...

Dave; Micky's does look like a 8.2 with that cover.. My Ventura has a 8.5 with the tabs pointing down on the cover... I will have to look more, as I thought the 8.5 was more common ... Micky, the name McKinnon was the place where the rear was built in Oshawa....
