measurement will be 42.625”. Final arm lengths seem to vary from around 32-5/8” to 33.25” depending on lift, axle squareness
(see step F), tire size, and gas tank clearance. Install adjustable end of arm to rear crossmember lower mounts with supplied
hardware (zerk on bottom).

with supplied hardware (zerk on top). The upper arms will be used to adjust final pinion angle.
