    Does anyone know if this will fit a 70 Buick GS 455 with a th400, factory flexplate? Not sure about the bolt circle size.

    TCI torque converter Part #241501 Chevy, TH400, TH375, TH350

    Say's it has a wide bolt pattern, 11.5" bolt circle.

    Jeff,
    I would think so, but to be sure, pm Meanbuicks on this BB. Greg works for TCI, he would know for sure.

    Yes, that'll fit the stock Buick 455 (and Pontiac) 166-tooth flexplates.

    Don't Chevy-type converters use a nut/bolt combo to fasten to the flexplate, instead of just a bolt like our Buicks generally use??

    Just a thought....doesn't keep it from working....just a thought.

    This one appeared to be from a TH350 with widerplates welded to it to make the bolt pattern larger.
