440 Source Flywheel

The one 440 source sells is a chinese knockoff of the one McLeod sells minus the sfi rating, the balance weight from 440 source will fit on the McLeod wheel and vice-versa, the weight is generic though as far as the actual weight needed to balance each engine that it is said to fit. As far as quality goes I'd trust the 440 source wheel more than I would trust a 40 year old stocker.
