Drill 3/ 16" mounting holes into the top of the housing. Start at the middle and every 24" toward the
ends. The holes should be about ¾ " above the back of the housing. Drill 3/16" mounting holes at each
end of the housing between the two pop rivets (top of housing back)
c.
Measure and mark the middle of the housing at the top area of the back of the housing

Before tightening fasteners to header, attach the front cover of the hood, ensuring the top and back
hood assembly is not bowed and you are able to satisfactorily attach the front cover. Once this is done,
remove front cover and tighten fasteners
