Is an Adjustable Torque Arm Needed?
(springs > ride height, etc.). Since you don't know
for sure about the 12-bolt's mounting hardware and
your final installed geometry, it's a deal where you
would have to measure pinion angle afterward, and
then possibly have to swap TAs in another session,
vs. doing it all at once (saving some aggravation and/
or shop time @ rate).
