As a general rule you never no what the factory might in, No to torque boxes on the 727 automatics, The Floor Hump for the shifter and "Z" bar mounting plate welded to inter body on driver side with also added to the manual cars (3 or 4 speed). A under body bracket for the duel exhaust was also added on the 340 cars (auto & 4 speed manual). Not sure if it was an option, but mine (4 speed) has a pinion snubber on the 8 3/4 chunk.
