Help in identifying a 69 12-bolt posi unit
 

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. https://www.yenko.net/ubbthreads/imag...lins/frown.gif

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!!!!!!!!!!!! https://www.yenko.net/ubbthreads/images/graemlins/no.gif


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 ! https://www.yenko.net/ubbthreads/imag...s/headbang.gif

Thanks in advance.
Steve
