a. Test fit the new spring hanger and grind smooth any other interfering bracketry. (If welding the
bracket on as well, mark and clean the desired areas of the unibody where planning to weld. The
new hanger should fit snug to both the unibody and the bottom of the body itself.)
b. Note that the fuel and brake lines on the passenger side will need to be slightly moved so the
hanger can fit flush to the unibody.
c. Positioning of the hanger can be done 3 ways.
i. Utilize the hole in the unibody where the old spring bolt went through and line it up with
the hole on the new spring hanger for the spring bolt.
ii. Measure 3.75” from the front of the spring hanger to the nearest body seam in front of the
spring hanger.
iii. The spring hanger should only be able to go so far forward as the unibody gets wider in
front of where the new hanger goes. Position the hanger as far forward as it can go, it
will butt up to the widened portion of the unibody.
