RARE! big bell housing from 78-79 El Camino with 350 4 speed. This is the correct bell housing with the lowered pivot ball position so you can use it in your 78-81 factory manual transmission A/G body cars. This allows using the big 168 tooth flywheel and 11 inch clutch. This unit needs to be repaired. It has a crack through the pivot ball hole area. There are also 3 holes that were drilled for inspection of the clutch. Sold as is. Feel free to ask any questions you might have.
