Oil Plug

[juicestain100]

I need a new oil plug for my base 3.8 2006 Grand Prix. What size is it and can someone please post a link to where I can buy one? It sounds like something easy to google but I keep finding ones for sales that are different sizes and want to make sure I get the correct size.
Thanks!
