Chevy Malibu 1999 Speaker question?

[hollisterjay2012]

Im wanting to buy some new 4x6 speakers for the doors in my '99 malibu. I know the size and depth, but not the screw pattern, like you know the speakers that have all kind of holes around it so it fits? the speakers I want only have one pattern on them, and here is a link to them: http://www.dealercostcaraudio.com/sps-406.aspx

Also, on that same site, do you guys have any recommendations for the ones in the back of my car (6x9s)
