      I have a GM posi unit I am trying to identify. The following
      numbers are cast into
      the carrier: F185, EDB 30162. Stamped on the carrier is: G2F6.
      It has a
      8.75" diameter 41 tooth ring gear, with the following stamped on the
      ring gear:
      4116 GM 7650. The ring gear has 12 bolts that hold it to the
      carrier. The axles
      are 31 spline and 1.3125 diameter. If anyone has a parts book or can
      ID this it
      would much appreciated. I believe it's from the early 1970's.
      Thanks Brian
