I am selling a used Borg Warner Super T-10 4 speed transmission, after doing some research it appears to be out of a 1976 Firebird behind a 400 or 455 engine. It has 26 spline input and 32 spline output. It comes with a Hurst Competition/Plus shifter (no stick). It was in great working order prior to taking out of my car, the reason for selling is I am upgrading to a Tremec TKO and don't need this sitting around. Here are the Specs.
