Lexus rebuilt alternators replace all internal components...with OEM components..the only thing reused are the Aluminum housings.

Big box auto parts doesn't disclose what parts are rebuilt or replaced....expect the worst.

Their lifetime warranty lulls you into thinking it is a quality rebuild.
So i need to change any wires or fuses or can i keep everything stock when i put the 430 alternator on?
