1990 Ford Bronco Custom Radius Arm Sketch - Front & Rear Suspension Arm Blueprint

This document is a hand-drawn design sketch, scanned from lined notebook paper, showing two fabricated suspension arms, one labeled "Rear" and one labeled "front." Both arms are drawn as long, tapered members with a series of round lightening holes along their length. The rear arm sketch includes a mounting bracket or gusset at one end with dimension callouts of 8 inches and 6 inches, and the notation "6² + 8²" (a Pythagorean calculation, likely for the bracket geometry) appears nearby. The front arm sketch shows a large round bushing eye at one end and carries an overall length dimension of approximately 54 inches. The page also contains faint mirrored bleed-through handwriting from math calculations on the reverse side, which is not legible. There are no part numbers, no vehicle year/model identification, no torque specs, and no material callouts visible. The document appears to be a concept/fabrication sketch, likely for custom long-travel radius arms or trailing arms for a truck suspension build, uploaded to a 1990 Ford Bronco gallery, though nothing in the drawing itself identifies the vehicle. A reader can learn the intended proportions and general layout (arm length ~54", bracket dimensions 6" and 8") of the front and rear arm designs.
