Mounting the Rear Leg Socket (45º Degree Tailgate Stop)
Insert the rear leg socket into the rear mounting bracket
plate 1 as seen in gure below (plate 2 will not be
used). 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.
For Toyota Tacoma, Chevy Colorado, or GMC
Canyon with a 45-degree tail-gate stop.
If the best mounting hole location is between
oor ribs, a oor spacer and/or two extra
5/16" at washers have been provided to ll
the void. Or rotate the leg socket 90° to the
rear of the vehicle if possible.
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 seen in Figure below. 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 to mark the front 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.
