The yokes.
Due to varying brackets I couldn't get these to line up perfectly but...remember those bumpers? Yup, you guessed it. Approximately a 4" difference. I can't explain it. Maybe the brackets attached to the fenders are different? Maybe there is enough flex in the fenders that they give enough to make up the difference? I only checked full width on these. I'll go back and measure from centerline-to-tip for each side on both. Maybe one of them is tweaked. Dragging all this iron around the yard had my Scoliosis demanding I call it a day. I just wanted to get this info out there and hopefully open up a little discussion on the topic. Any suggestions or hypotheses?
