No, thick part would go to the back to increase caster.

Glad it helped. Note that while increasing the caster to 6-8 degrees like the newer straight axle trucks can be beneficial. It does point the pinion down and increase driveshaft angle. Can cause interference in the CV at lifts 4" and over. A CV actually has less max operating angle than a single u-joint. Good idea to check for binding at full droop (axle hanging) after changes are made.
