Did you count the teeth on that flywheel or did you Ass U me it was a 143 tooth? The reason I'm asking it looks a lot like the 170 tooth hemi flywheels did on the back side If it is a larger diameter flywheel for a 12 inch clutch your going to need the correct bell housing and starter for the starter to work on the bigger flywheel
