Extreme clutch shudder

Curious, if the alignment tool was off, screwed up either by design or user error, and it pulled out fine and the trans slid in fine.

Would the disc align once the clutch pedal is depressed?

I've always aligned the disc, but also always wondered why I'm relying on a piece of plastic to align machined metal surfaces, and the consequences of doing so.

I've always been lucky, broke enough stuff to have a hosed up input shaft. Somewhere, I still have the cut-off shaft out of my 69 383 RR with a loop welded to the back. Unfortunately, that did me no good with the 70 440-6 which is 18 spline.

The DO MAKE metal alignment tools...............I have no idea where mine is made by Lisle, I think

You screw the correct pilot on the end, and off you go
