69 Barracuda Clutch Shake Help Needed.

I maintain its the clutch/flywheel,.. re-remachine the flywheel, or try a different one.

It's really painful watching someone go thru something you been thru a few dozen times cuz the customer was too cheap to machine the flywheel, and then had to re-do the job in order to machine the flywheel true, to correct the "shudder".

I realize you had it resurfaced, but machine shops make mistakes too, trust me, I've come across lotsa incorrect machine work. One piece of grit on a mounting surface ..

And then there's the clutch interference issue.. to me that's a flag there's something outta proportion there, and be more curious about that.

IMHO you're chasing your tail trying to cure symptoms, instead of the fundamental cause, power is being transffered to the drivetrain in an inconsistant manner.

The spring motion is a visual representation of the power being received. Smooth power transfer, the spring would remain evenly torqued.

good luck..
