Does anyone have a part number for or a place to buy this return spring? It's the one that goes between the tab on the bellhousing and the clutch fork itself...It seems like the ones I can find online are for small-blocks, and I'm not sure if they're the same. I just cut a generic spring, but it's a little heavy at the end of the travel and a little light at the beginning, so I'd like to find a factory style one.
