1996 Ford Bronco/F-150 Frame Dimensions - Underbody Misalignment Check Diagram

This document is a Ford factory-style frame/underbody misalignment check blueprint (drawing number N13581-A) showing a full-size pickup/Bronco-type ladder frame in two views: a plan (top) view with diagonal cross-check and width dimensions, and a side elevation view with height (datum) dimensions. Twenty numbered reference points (1-20) run along the bottom of the drawing, keyed to vertical measurement stations on the frame rails. All dimensions are given in inches with millimeter equivalents in parentheses, for example, longitudinal spans of 38.8" (984 mm), 38.1" (968 mm), 14.7" (375 mm), 33.8" (859 mm), and diagonal cross-measurements such as 61.6" (1565 mm), 62.1" (1579 mm), 55.2" (1402 mm), and 50.3" (1278 mm). Side-view datum heights range from roughly 7.0" (178 mm) at mid-frame to 17.1" (435 mm) at the rear. A technician can use this chart to check a frame for collision damage or misalignment by comparing measured point-to-point and diagonal (X-check) distances against the specified values. The scan was uploaded to a 1996 Ford Bronco gallery with a filename referencing the 96 F-150; the drawing itself carries no visible year, model, or engine identification beyond the drawing number.
