    Will this work with a th350 that has overdrive?

    Asked by: Goose2210
    These do fit TH350, GM did not produce a TH350 with overdive.

    Would this work with a stock LS flexplate? If not could you list the item number of the flexplate that it would work with. (This application would be an LS backed by a th350)

    Asked by: Mark777
    You must use a converter spacer that gm makes.
