I just finished TIG welding up three road draft tubes for a local enthusiast who's converting all his 235/261 rolling stock to a setup just like in your photo. So not everybody wants to give up the "waste oil delivery" system. I hear it keeps the garage floor a little cleaner. "Just a Six" is right, though, the inside of these is really loaded with GOO, welding gets pretty smokey. Try to soak it for a week in something really mean.
