Thanks guys. The engine is cammed up to the point that it vibrates the car pretty well, especially at idle (1K RPM). I've taken the car up to 60 mph or so and thrown it into neutral in an attempt to isolate the shaft from the engine. I still feel some vibration. I'm leaning more towards the rebuilt driveshaft. The whole driveshaft assembly is only about 18" long. Could the adding of the balancing weights have a noticable effect on the ride with regards to vibration? Perry has me worried a bit in that it looks like the same guys did a job for him and never got it right. Changing a shaft is so easy compared to replacing the flywheel, I think I should convince myself that the shaft is not contributing to the problem. Everyone agree?
