I have for sale a pair of shocks that were removed from a vintage shovelhead chassis. To the best of my knowledge these are OEM parts. If there is something I can check for you to confirm that, let me know. One appears to be in good condition. The other apparently began to leak a little during this last season. The leak must not be bad as I didn't think the ride quality changed and I didn't even notice any signs of the leak until I removed them for shorter shocks in the fall.
