    Midyear frame hole question

    On a midyear frame what is the diameter for the holes for the rear muffler hanger? These are the holes that would be presumably untouched on a sidepipe car.
    thanks

    I'm measuring 11/32nds hole (for a 5/16 bolt ?)

    GM spec usually has a min/max diameter tolerance.
