Cheap/inexpensive street clutch

I think you already did. And what RRR said, I echo.
The clutch is not a place to cheap out. The domelight,maybe.....But if you are just gonna slam a cheap clutch in there to make the car saleable? Well,that would be a whole nuther can-O-worms.
And as to reinstalling the spring? That's a poor way of selecting a clutch.This I might understand if you have physical handicap.But in all seriousness, putting the spring back on is just not that big a chore. Plus at the cheap-clutch level, you might get away without it anyway.
In any case, you might just have the cheap-clutch thing cornered already; just buy a disc and slap it in there PressurePlates can be reused, if physically sound.
