Need Pic F body 12 bolt BE

[Unreal]

The lower E means it had an Eaton posi unit in it. Note that that E looks similar to the E in BE. Hard to tell from the angle, but I'd check it out anyway. Casting date seems early for COPO, though.

were some of the early yenko vins in january of 69?

perhaps JM or eric would have an opinion

Alan,
I thought the 1st Yenko order was placed in Nov 1968 and the first cars were 01C or 01D bodies.

Does anyone know what rear dates were in the 1st two ZL1s?

I ran a pencil over the E for eaton today and the E in the BE they are identicle type set, but the E is deeper stamp on the eaton, most of the numbers on the tube seem to fade at top, Im guessing the roll of the tube?? I did pull it apart today to clean next week and set the gears up in it. I have not found anything on the internet that "BE" was to specific to "COPO" but just 4:10 gear ratio and possibly a service part??? I do not know I'm no expert on this. The car does have a multitude of what seems to be "counter parts" I just figured this was the same as well...

Your top E looks identicle with the deeb lower case and top fade, appers to be the same type set almost same looking stamp. well what ever mine is it's a 12 bolt....

the edge of the ring gear should have a GM part number on it if it's an original GM part, that number will tell the story. the posi carrier might have a three letter / numeral code stamped on edge of the ring gear flange or the counter weight pad on the top of the carrier.... that info will be helpfull in establishing more clues about the origins of the rear.

Those BE stamps do look similar so probably not a restamped BL. The 1001 date code is incredibly early for a COPO car. The casting date lines up with the stamping date but the first COPO's were late Dec so if that rear is legit, it would be from a very early COPO most likely if not from a prototype. Has anyone seen a BE rear dated earlier than Dec? Could be an interesting find.

I think the "E" looks deep in lower case as well as the "B" given the area of the tube it was hit, Charley's rear in pic the upper E was hit on the down side the eaton E was hit on the upper side giving one deep on lower case and one deep on upper case. Stamping a circumference with a smill die will give variance on direction hit and location, whether more parallel or vertical on the tube. A simple pencil scribe next to each other on paper will tell type set.
