What view does this blueprint show?

It is labeled "View Looking Up," showing the underside layout with Passenger Side on the left and Drivers Side on the right, referenced to a centerline (C/L) and Spindle C/L.

How far are the rack-and-pinion (R&P) mounts from the centerline?

The left R&P mount centerline is 6.7500" from center and the right is 8.7500" from center, with vertical offsets of 5.9687" and 3.7187" shown.

What angle are the lower A-arm centerlines drawn at?

Both sides show an angle of 74.1150° relative to the layout.

What is the spacing of the lower mounting hole pairs?

Each lower mounting hole pair is spaced 2.0300" apart, located 14.4075" and 16.4375" from the centerline on each side.

Who made this drawing and when?

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.
