    you're welcome to try, but since I build and race these, you might find me a bit hard to convince...

    Well it's gotta provide --a little-- but I know what you're meaning.

    I've been hanging my coupe body (sans front clip) by the corners at the upper windshield posts (and at rear window corners) and without the T-bar I don't think I'd do that on a convertible, but talking about ultimate strength where stuff bends, and flexibility within the material springback where stuff shakes, are indeed two different things.

    jack the car up behind the front wheel on the frame then open the door... there is twist there but my point was following yours - that the little T bar provides nothing in way of strength to the chassis.

    NTITEB (That means NotThatI'mTheExpertBut A photo that to me shows that coupe or convertible, doors are part of a structural "path" of the C3 body; opening and closing wear alone cannot account for how pounded-to-pieces these hinge bushings from my '72 are. The triangle of the upper and lower hinge on the door post, and the latch at rear, is likely part of what prevents cowl shake and all points need to be snug when the door shuts. I.E., my car even though a coupe would probably shake if I just stuck these back in without repair.

    you know this but this fits within the conversation.... most C3s, which are race cars, started as convertibles. Not just that but the issue is the flexing frame and top or not, it doesn't matter for strength because, as Loren points out, that little bar running to the targa top does nothing for torsional stiffness.

    I think you could answer this question by simply looking in the mirror.... the only number-matching that happens here is the one to check whether or not the part is stolen.

    the rear header and t-top center bar to windshield.

    however, as i always say-- i know what *I* would do, but its
    your car, your money. up to you how you want to do it....

    There's two frame mounts each side in the cowl area to look at if there's shaking. It's all sheet metal under the 'glass through there, windshield, door posts, rockers.

    not sure the sun came up today... I've driven it, it is nice - like driving a gated manual.... very precise. Not sure I like the ability to adjust pressure off center - it has springs that return it, in neutral to the spot between 3rd and 4th because it makes reverse a pain to find (below 5th but you have to put a bit of pressure to get onto that gate side (or 1st/2nd). Outside of that, it feels very positive in both gear selection and holding power in those gears.

    no, that's a friend's car that I've driven.... I told him that if he dies, I want it
