    Is it 47mm? I could have sworn it was a hair smaller at ~45mm or something.

    Thanks

    Thank you Steve.

    Any recommendations for a chrome replacement knob closer to OEM size?

    I used a Hill knob in my old 328 but wanted something closer to OEM size for my TR.

    No trouble -- but what deviltry are you plotting ;). Are you considering going larger or looking to match stock?

    Ideally match OEM stock in terms of size or maybe a hair larger. Definitely smaller then the 46/47mm knob I used to use.

    Interesting that the original ones had no.s printed with paralax error taken into account .Repros don't.
    Always thought this was a really neat feature.
    Hard to explain unless you have both next to each other

    No, the chrome knobs are 47mm and I don't believe there is a small version planned.

    I just realized the factory F512m shift knob is all brushed Al. (PN 162614).

    Does anyone know what its size is? My research points to maybe 46mm? (but no confirmation)

    Thanks

    My black 43mm one showed up the other day. I'm very happy with it as well as the Oreo's ;)

    Actually curious: do you any PN 162614 knobs for sale? How much?

    I am trying to price them from different vendors.
