fs5r30a

I can't seem to find a rebuild kit for my transmission anywhere. my '02 S/C has an FS5R30A 5spd manual trans in it, and the 2nd gear synchro is wearing out big time. Everywhere I look, I see rebuild kits for the FS5R30A, but they all say they are NOT for the supercharged Xterra. Am I missing...
