Andy's (ADM) 4L80e adapter plate showed up today, this bastard is HEAVY and solid. Weighs as much as the entire factory crossmember, must be solid steel. Can't ask for a simpler way to bolt in a 4L80.
@Padre, lexan isn't DOT legal for front glass, but is legal in the rear. It's legal f/r on a dragstrip.
