6.5s in the door (if you're fitting them under the stock speaker grilles you'll have to get a shallow-fit speaker), 3.5s in the dash, and I have 6x9s in the rear of my '92.

If you go to crutchfield.com and enter in your car's information and they'll show you which products they have to fit everywhere on your car.
