Custom Crossmember Bracing Sketch - Frame & Mounting Point Diagram (Ford Bronco)

Structural schematic comparing original frame design to a braced version with color-coded frame, supports and crossmember.

AI caption · Photo 343 of 466

This document is a hand-drawn digital sketch (not a factory schematic) comparing two crossmember designs, apparently shared as advice in an automotive forum context. The top drawing, labeled "Original Design," shows a simple, mostly flat crossmember spanning between two frame rails. The bottom drawing, labeled "Your Design with PROPER bracing idea," shows a modified crossmember with a stepped/dropped center section and an additional boxed section wrapping around the right frame rail. A color legend identifies the elements: the frame rails are drawn in blue, supports in red, the crossmember (Xmember) in gray, and mounting points in green. The accompanying note advises: "Try to add a vertical plane across the ENTIRE crossmember. that will make it plenty sturdy enough." A reader can learn the suggested approach for strengthening a custom crossmember — extending a full-length vertical plane across it rather than relying on the original flat design — and can see where the supports and mounting points attach relative to the frame rails. The document contains no year, make, model, part numbers, or dimensions; it was uploaded to a 1984 Ford Bronco gallery but does not itself state vehicle applicability.

It recommends adding a vertical plane across the ENTIRE crossmember, stating that this "will make it plenty sturdy enough."
How many designs are compared in this document?
Two: an "Original Design" flat crossmember, and a revised "Your Design with PROPER bracing idea" showing a stepped crossmember with added bracing around the frame rails.
Does the document give dimensions, part numbers, or vehicle years?
No. It is a conceptual sketch only, with a color legend and a bracing suggestion, but no measurements, part numbers, or stated vehicle applicability.
