This is a CAD-style dimensional blueprint titled "View Looking Up," drawn by D. Rahn and dated 1/2/2011. It depicts the underside layout of a front suspension crossmember/K-member area, showing the passenger side (left) and drivers side (right) relative to a vertical centerline (C/L) and a horizontal Spindle C/L. Marked features include the Lower "A" Arm centerlines on both sides, rack-and-pinion (R&P) mount centerlines, and several mounting hole locations (drawn as small ovals/circles). Numerous precise dimensions are given, such as R&P mount offsets of 6.7500" and 8.7500" from the centerline, angular measurements of 74.1150° on each side, lower A-arm pivot dimensions (9.3438", 6.6250", 3.2500", 3.0395", 3.0000", 11.8823"), driver-side dimensions (2.4062", 4.4568", 16.9688", 16.6625", 12.5133"), symmetric mounting hole spans of 15.4063", 14.4075", and 16.4375" each side of center, and 2.0300" hole pair spacing at the lower mounts. A reader could use this drawing to locate or fabricate suspension mounting points, verify crossmember geometry, or position a rack-and-pinion steering unit. The drawing itself does not state a vehicle make, model, or year of applicability.
