If you need an amber bubble light to go with the kits, use NSN 6220-00-947-7570.
M
echanics, make sure you replace a missing or torn nylon cover, NSN 4030-00-
594-0475, that fits over the truck’s tailgate chain.
This cover, known as a guy protector, has sever-
al purposes, including sound deadening, rust pre-
vention, and finger(s) protection!
But the cover is a little tricky to slip over the
chain, which is one reason why it’s not replaced
when it gets damaged or deteriorates.
Make the job easier. Straighten a metal coat
hanger and hook the end through the last chain link.
Some mechanics have used a battery hold-down
bolt, NSN 5306-00-739-7754, hooked to the
chain’s last link, to thread it through the cover.
