I just did some quick research and it looks like there isn't a specific after market speaker that will exactly match your stock speakers. It lists the largest size that will fit in the holes as follows: Front doors=6 3/4", Rear seat side panels=6 1/2". I suspect you may need to drill some new holes and/or modify your speaker holes.
thank you
