1979 Ford Bronco Rock Slider Profile Sketch - 4 Cross-Section Design Options

This document is a simple hand-drawn schematic sketch, not a text-based reference. It shows four vertically oriented profile shapes labeled 1 through 4, arranged side by side. Each shape resembles a cross-section or side-profile of a slider or rocker-guard style component, with a curved bulge near the lower third of the profile. Shape 1 includes a red vertical reference line running through its length and has horizontal segment lines, suggesting it may indicate a mounting plane or reference datum with attachment points. Shapes 2 through 4 show variations of the profile: shape 2 has a rounded lens-like bulge, shape 3 has a smoother outward sweep, and shape 4 shows only a slight step near the bottom. Given the upload filename 'sliders.jpg' and its placement in an album for a 1979 Ford Bronco, the sketch likely represents design concept options for rock sliders or body-side protection profiles as seen from an end/cross-section view. The document contains no dimensions, part numbers, wire colors, fuse data, or written annotations beyond the numerals 1-4, so a reader can only learn the comparative shapes of the four proposed profiles.
