Engine cover push pins. Pontiac Vibe. 2003

We needed to fix mum's car:- prints push pins which hold engine heat cover onto engine. Just a supporting role.. there are also two real nuts holding it down too. Push two of them in to replace car rearward pins on Pontiac Vibe 2003 plastic engine cover. Unsure if ABS will be OK on cylinder head, but these replace weak nylon push pins.
Update: Pins have worked for a week and are solid.
