Help in identifying a 69 12-bolt posi unit

[nuch_ss396]

Hi guys!

I'm in the middle of rebuilding the 12-bolt rear out of my
69 SS Camaro and I ran into a snag of sorts. I failed to
purchase the necessary components to rebuild the posi unit
itself. So, I called the supplier (DTS) today and this
is where the snag began.

From what DTS told me, there were several posi unit
manufacturers back in the day and some of the unit
components are no longer available. SNAG!!!!!!!!!!!!


OK, I can't tell if I have a GM or Eaton, or etc. posi
unit. The casting numbers I got off of the 3 series carrier
are: EDB-30140 1, then an 8 8 number which looks like a
casting date ( August 68 ). The 12-bolt is a 3.08 posi
that came out of an early build SS 396. The 12-bolt housing
has a late August 68 casting date as well and I believe the
posi unit is the original unit.

Can anyone help me identify the posi unit I have based on
the numbers I posted? I can tell you that this posi unit
has four coil-type springs about 1.5 inches long ( in their
compressed state ).

Lastly, if DTS can't supply me with the replacement posi
internals I need for this rebuild, can any of you suggest a
source? Please don't say eBay !

Thanks in advance.
