i have a delsol and i am trying to remove the rear bumper. the part where my license plate goes i can't get off and i have removed all of the bolts. but there are these 2 things shat kinda look like studs but i cann't get them off. if anyone can help please post up

 

did you take the plastic cover inside the trunk and pull carpet back and see whats on the backside of them??

 

take out the carpet lining in the trunk, you'll find 5 nuts. no need to remove the license plate panel. i just did this last week.
