The pins are on top to hold the plastic cover that houses the wire harness
that goes across the top of the SC. You put them back where you took them out
Take the plastic wire harness cover, put it in its relative position with the hinge side towards the radiator. Then put the ones with pins in the respective holes.
Loctite 510 is the sealant, it'* not that easy to find. i found mine at Motion Industries where I found the bearings. You run a bead 1/16 " around each hole on the snout side and connect the circles.
