I have a 68 coded, was told by the Pontiac man "68 gto" Muncie freshly rebuilt new bearings and seals. All gears were inspected and no chips or issues seen. Ran it for 950 miles before swapping to an overdrive unit. Not sure what its worth but I am open to offers. If interested I can send some pics. My email address is
