The facelift headlamps have the beam converters built in, you just have to move a small lever inside each headlamp and it removes the raised part of the dipped beam that would otherwise dazzle an oncoming driver
I know they're there as I tested both last week when I fitted a new radiator & A/C condensor.
Spare serpentine belt is in the boot, however I fitted a new one a few months ago when I replaced the crank pulley (Corteco
).
