Extreme clutch shudder

I mentioned this once before, do yourself a favor. Buy 2 long trans bolts say, 4 " or 5" , cut the heads off and screw them into the top two trans holes for guides when pushing the trans in. They just straighten things out. Easy install, and if you get tired, they will hold it while you recover.
Also, you did have a clutch alignment tool to center the disc?
