frame where the axle mounts.

INSTALLATION

This kit is designed for use on Dingo Model 22304,
serial no. 890100 to 891033, to provide front axle
retention and alignment.

the frame. Center punch each of the holes at the
locations marked on the template.

6. Drill a 17/32” hole at each of the four marked
