904 from 66 on is a lever action shifter. The aftermarket shifters all use a cable to manipulate the sector shaft lever on the side of the 904. The OLD 65 used a true cable as in it went into the valve body as a cable and did not have a sector shaft coming up through the case outside the kickdown lever. The aftermarkets will include a bracket to mount to the pan rails to support the new push/pull cable that fastens to the arm shown in this FABO photo. No aftermarket shifter will mount to the existing welded tabs on the tunnel
