The attaching tabs are punchouts that stand 90 degrees out from the molding's integral reinforcement. They were designed to pass through mounting holes in the hood and secured by bending another 90 degrees around to the underside.
They are very thin - from my experience you may get one or two unbending / rebending for removal and reattachment - then they break off.
The openings in the reinforcement are very shallow, making other mechanical attachment difficult. The holes are also too small for most molding "T" clips. Use of screws often results in dimpling the molding when the tip of the screw contacts its underside. I believe the reinforcement is galvanized, making welding replacement tabs onto it a job best left to professionals. I have also seen tabless moldings attached with two sided tape.
