STEP 2A
Note:
Take the rear leg socket assembly, four 5/16-18 x 1-1/4"
hex head bolts, four 5/16" lock washers and four 5/16"
at washers and install as shown in gure below. (It may
be necessary to dis-assemble rear mounting bracket plate
1 and 2 in order to fasten plate 2 to the truck). Tighten all
fasteners at this time on the rear mounting bracket.
Take a 3/8–16 x 1" thread cutting bolt and install into the
rear mounting bracket as shown in the gure below. Tighten
the thread cutting bolt enough in order to mark the rear leg
socket for drilling.
Disassemble the rear leg socket assembly taking the rear
leg socket and drill a 7/32" pilot hole through the mark
created in the previous step with the thread cutting bolt.
Then re-drill the hole using a 1/2" drill bit. Reassemble
the rear leg socket assembly to the truck bed tightening all
hardware except the 3/8-16 x 1" thread cutting bolt.
Using the 5/16-18 x 1" hex head bolts, washers, and nylon lock
nuts fasten the rear mounting bracket plate 1 and 2 together.
The long end of the angle on plate 2 faces away from plate 1.
Insert the rear leg socket into the rear mounting bracket
assembly. Hold the mounting bracket assembly ush with the
tailgate stop ensuring that the rear leg is plumb and square to
the truck bed.
Mark the ve holes. Remove the assembly and center punch
each of the holes. Drill a 7/32" pilot hole, then re-drill each
hole using a 1/2" drill bit.
Install blind fasteners into each drilled hole.
