Brake rotor size problem '04 Taco

Okay so here is the scenario. Awhile back I was doing a brake job and at the time I hadnt really taken the dive into modding my Tacoma. I went to the local autoparts store (Advanced Auto Parts) and picked up everything I needed.

When I took everything apart it was going really quick. I barely finished half my first beer by the time I was ready to reassemble the driver's side. Except when I went to put the caliper back I noticed that I couldnt get it on correctly and the bolts werent lining up. I scratched my head then pulled the rotor off and lined it up on top of the original. Sure enough, the ones I got were just a few mm larger in diameter.

I checked a couple other places around town and found the same oversized rotors. I eventually just had to have the originals turned down. Of course that was 6 months ago and the brakes are beating the heck out of me now. I just didnt have the time to wait at that point.

Has anyone encountered the same problem and can you tell me what size I need exactly? I went to autoanything.com and looked at rotors but for an '04 they just have one size rotor. I dont want to end up in the same situation as before.

Also, any recommendations on the 'best bang for the buck' rotors and brake pads I am all ears.

Thanks
