    You can add to the list the "heavy-duty rubber bumper guards" (01/73) + "Extra reinforcements in doors" (01/73) + "Simulated leather steering wheel" (Not US specific and for T only)

    emblem on dash for flasher went away sometime in '73.

    Gusseted bumper brackets appeared in ' guess is they appeared at the same time (1/73) as the bar reinforcements in the doors...but I am not sure

    This should be a pretty cool thread. I have found quite a few things were different '72 - '73 as Porsche got their arms around the upcoming '74 safety regulations.

    I am sure Mr. Mayo has a laundry list

    IIRC, Several items were mandated by '73 safety regs. (went into effect for U. S.-destined cars manufactured after 1/1/73-not model year). Hence the mid-year changes.
    Most visible were front crash standards.
    S Reg #1032

    You can add deletion of rear seat belts around January 1st 1972.

    My 1972 911-T that was delivered to the dealer in May 1972 still has it's original rear belts (1969 labels). Of the 2931 built 911-T coupe U.S. cars, my SN is 2154.

    My late January of 72 build T #1128 never had them installed. My car still has the black plastic plugs in the holes. It sounds like maybe your car had earlier seatbelts put in it which from my understanding was the only way to get rear seat belts in cars built after January 1st 1972. Perhaps others could chime in.

    Hi Dirk

    Nice list. Is this from factory production records or compiled from observing examples. Think I recognise source of some things in list.

    One point. Not sure about the US market specifically...but pretty sure generally accepted that Bosch Fanfare (aka Banjo) is horn set that preceded the use of the different trumpet shape Stritones (or the very similar Klaxon in some cases) during December 72. This horn switch has been researched elsewhere based on range of period documentation, photos etc.
