you can buy those from Ford it’s actually not uncommon for them to break when putting your headlights back in. My buddies actually keep spares for that reason with that said I have removed and replaced my headlights many times without breaking mine. Knock on wood! It’s really about being careful when putting them back in lining up the clip helps as it’s in a slotted hole that allows it to slide a bit forward or backwards . I usually slide the clip all the way forward as that’s the direction you have to move the headlight when putting it back in.
