Mating LS427 to T56...

Did you install the trans to the bellhousing before bolting on the clutch, like I suggested?

I did. There were no issues there.

I suspect what is happening is that your disks are not lined up square. When you insert the alignment tool, you have to maintain forward pressure on the alignment tool, as centered as possible, as you snug down the pressure plate bolts.

I feel like I did that. There was some lateral play when doing so, so I intentionally pushed forward and tried to visually maintain straightness when I tightened down everything. Again, I can push the alignment tool all the way in at this point with no issues at all.

So you're saying the shaft should go in pretty easily then? Again, I didn't want to go beyond a comparatively light-handed try until I got more info.

When everything is lined up, it all just pops together pretty easily. That's the point of all the alignment steps that you went through. Nothing should be binding.

Do you have a yoke on the output shaft? Having the trans in hear while you wiggle the yoke can do the trick.
