I'm really thinking on buying the cheap plastic thing to save some money...
DON'T!!!!
I've broken 2 of those damn things within 3000 miles. And of course it always happens when you're not expecting it. After the first time I wouldn't leave with the car without a spare one in the glove compartment.
If your willing to pay the cash for a clutch like that, pay some more and get a decent quadrant which won't break and leaving you without a clutch at the side of the road.
It isn't expensive at all so order one......
