Chevy vs Ford Front Spindle Comparison Diagram - Dimensions & Differences

This document is a dimensional comparison blueprint of two front axle spindles, one labeled CHEVY and one labeled FORD, drawn side by side in profile. The Chevy spindle has an overall length noted as 6 1/2 while the Ford spindle is noted as 6 1/4. The Chevy spindle carries specific decimal dimension callouts for its stepped diameters: 1.625, 1.72, and 1.785 for the upper machined sections, 2.5 for the larger step near the base, and 3.37 across the mounting flange area. A base step dimension of 1 3/16 is shown on the Chevy side, versus 15/16 on the Ford side. Leader lines with the label SAME indicate that the upper stepped bearing sections of both spindles are identical, and a second SAME label indicates the mounting flange/base sections are also identical between the two. A DIFFERENT label points to the intermediate step (the 2.5 area and the 1 3/16 vs 15/16 heights), showing where the two spindles diverge. A reader can learn which spindle sections interchange between Chevy and Ford units and which dimensions differ, useful for hybrid axle or spindle swap projects.
