    man they musta been smokin the good stuff at gm when they laid out the bolts for a th400 tail housing.... you know, the 6 bolts on the back of the tranny?

    NO theyre not based off the same radius
    NO theyre not evenly spaced
    NO theyre not symetrical
    NO theres no rhyme or reason to it :)

    anyone have any detailed white papers or specs on the layout of those bolts? I can get it done, but Id rather see what someone else came up with..

    Im having a "special" adapter/spacer made for it and I have to sketch up a detailed plan of the work I want done..
