my little hydraulic things on the trunk and hood dont work anymore where can i buy some of these to replace them

 

Yes, most major chain parts stores have them. Be sure to get ones with a lifetime Warr. sometimes they only last a couple years and they're dead again. I got mine at Kragen. I've also seen them at pep boys and AutoZone. I think the fronts were like $30 ea the rears $10-$15 ea.
