    I need to verify the hardware need for the conversion. I understand the write ups and the gaskets, bearings and seals. I need information on the bolts other than the 3/8 for the plate to tranny.

    What is the size of the studs and long bolts pictured on the Spaceghost page?

    Thanks for the help.

    5" grip length, 7/16C thread. 3 needed.
    Studs are Napa st52, 7/16Fx7/16Cx2" 2 needed.
    7/16F lock nuts, get the crimped ones, not teflon lined. 2 needed.

    Flat washers and lock washers, for the long bolts, flat for the short ones.
