Where to buy Kia Sorento 2005 clutch assembly aside from casa?

Hi guys,

Need to change my clutch assembly, sliding na daw yung clutch as per mechanic. Maingay na yung tunog nya pag naka idle yung sorento ko. Kala ko dati ingay lang ng makina dahil diesel. But i noticed n pag inapakan ko clutch nawawala yung kalampag na sounds. Now my problem is nagpaestimate ako sa casa. It will cost me atound 46k for clutch assembly pa lang wla pa labor. Can I ask po sana any recommended auto parts na nagbebenta ng mas mura but quality na clutch assembly?

Btw my ride is sorento diesel 4wd.

Thanks in advance.
