the tailgate stop ensuring that the rear leg is plumb and
square to the truck bed.

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
