Grand trapwork springs work well but an even lighter spring will work.  I
picked up a bag of springs at a hardware store (I'm not sure which one) a
few years ago.  I imagine just about anything will work as long as it's wide
enough that it doesn't pop out of the socket.  The only function of that
spring is to lift the pedal, beyond that it just adds resistance to the
mechanism.
