Its important to note that the picture posted above is not the original instructions to these bushings and is not included in their box. These bushings were originally released by Moog to address camber issues in fatigued cars, so the OEM instructions were set up to support an increase in camber, not caster. The last set I picked up a few weeks ago still show this.
Its only over the last 25-30 years that we have started using these to address caster adjustments which requires a different set-up, which is what the instructions posted above address. The instructions above were created by a member on Moparts in the 90s and have been distributed world wide ever since.
If you took a couple of boxes of these to a shop and asked them to install them, odds are they did it per the instructions in the box, not what is pictured above, unless you removed the original instructions and gave them this exact illustration.
