Third member, axle shafts and rear disc brake kit are shown in the photo for reference only, but are not included as part of this kit and are available separately.  When installing into a 1954 frame, due to the slight differences in the 1947-53 and 1954 frame, additional installation modifications will be required for the install into the 1954 frame at the shock crossmember area with regards to the width.  Please note that this is applicable only to the 1/2 ton chassis application and will not fit the 3/4 ton chassis applications.
