tighten the two bolts on that side. work with both sides so you get the gap where you want it on both sides and the rear (front to rear hood position). the female threads up in the hood part, that threaded/welded boss maybe loose/broken off and or the threads themselves stripped if it ain't holding an adjustment after you tighten the bolts. if they are just loose & need tightened then snug em & shut the hood & if is lined up right & repeat as needed then open the hood & tighten the bolts completely & your set. only caveat dont shut the hood all the way if it is shifted over enough to where a hood edge will catch the fender and or firewall top whatever it is called (valance?) & contact/scrape the paint
