1070GM Positraction I.D.
- Mar 3, 2004I 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
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.
