Extreme clutch shudder

He's right on this. When I replaced the clutch in my 64 Valiant after I first got it, I put the disc in backwards, because I was in the dark and wasn't paying attention. It will install backwards. I did it.
I don't know mine is a 10 and a half inch clutch and I have a act technologies clutch and desk and also a Hayes disc and if I put the Springs towards the flywheel they'll hit the flywheel. It won't lie flat on the flywheel. Maybe it's the make of clutch or something like that but both of my disks the more protruded part goes inside the bigger circumference of the pressure plate... I guess it's theoretically possible to clamp the pressure plate over top of it but it would seem like it would just block it in there and I would have a major problem...
And even if I'm 100% proven completely wrong about this I don't need somebody's big potty mouth putting me down and talking a lot of Internet hero crap... (not talking about you triple-r) I try to tell the truth about my experience to the best of my knowledge...
