Westin30-0005 Light Bar - Black

I have a 2002 dodge dakota 4door slt do i need a kit to mount it on my truck or all i need it's the bull bar ?

Does it fit a 2006 acura mdx? i saw a honda similar to acura with it installed.

Will this fit a 2004 ford explorer sport trac? And if so where do you get the installation kit?

Do i need to buy an additional mount kit for a 1998 rav4
