Hauled home "brand new"... yes "NEW" - "NOS" - US gear OD unit. Never installed. The install kit is for a 2WD C6 p/n 80-80026 and the OD unit itself is p/n 170-48080. The OD unit shows it works with 4WD and 2WD models up to 2003. Not sure what the kits require or if it's a direct T/C mount. Nice looking outfit, I am not sure if I can keep it. I already did a differential gear swap so my RPM's are manageable now. If you have any questions or interest shoot me a PM. If I were to let it go I would rather it be to an Oil Burner than the open market. I just don't know if I would gain that much in economy or engine life - most of my cruising is at 65 at or near empty.
