Abstract: An improved tapping plate and retention bracket assembly adjustably attaches a member, by means of a threaded bolt, to a web pedestal formed in a vehicle body frame. The bracket is formed from a single blank of sheet metal for enclosing a tapping plate, having a threaded bore for receiving the bolt, with the plate adapted to slidably seat on a central section of the bracket for controlled movement thereon. Forward and aft tongues, which extend from respective forward and aft transverse edges of the section, are adapted to overlie forward and aft frame web portions for welded attachment thereto. The bracket tongues, in addition to reinforcing the horizontally disposed pedestal, provide the sole means to secure the retention bracket to the pedestal, thereby obviating welding distortion of the bracket central section and the pedestal.
