Need A Template...

Hey everyone. I'm constructing a rear speaker deck for my 1986 Corolla fastback (yea, its too cool to be a hatch!). I'm using 1/4'' oak ply(maybe not the best stuff to use, but it looks fine to me), and am planning to place the 4 Pioneer 6''x9'' speakers in it. They were originally in custom (yea, custom! haha.) boxes with very ugly holes.

I've looked through the boxes and everywhere online, but I cannot find a 6''x9'' speaker cutout template. If anyone knows where I can get one, it would be appreciated if you could let me know. I've tried google, ask, msn, and alot of others...but sadly, nothing.

Please post any scans, pics, online sites, where I can get one, I could really use it. Thanks.

Why can't you just turn the speaker upside down on a piece of cardboard and trace it then cut it out?

that wont work. because the mounting plates are built into the speaker itself. so ill have a hole big enough for the hole speaker to fall into, not slip into tightly for me to screw down.
