Hey, so I just bought myself some Charger RT rims (18" with blacked out pockets) but they do not include center caps

Just had a few questions about them...
1) How do the caps attach to the rim? (I'm pretty sure they just snap in but want to make sure.)
2) What are the proper dimensions of the caps I'd need to buy?
3) Do I have to take the wheel off the car in order to put the caps on or can I just snap them in whenever?

Would these mopar caps fit?

Or would I have to go with something like this?

Thanks for the help

The Mopar caps should fit fine and they just snap in from the front and the wheel does not need to be removed.
