Hi, I have been to several websites that provide the honda parts catalog online and still have a problem finding out what parts i need becasue they are providing 2 part numbers for the same part. I have called one part desk(southbay honda) and they were guessing which part i needed. even with the VIN# they can't tell. I need a front left and right seat belt buckle for 2004 CRV EX. here are the numbers for the Right side... 04813-SCA-A01ZA 04813-S9A-A01ZA SCA? and S9A? what's the difference? please help, Greg.
