Ryan.....like I text you this morning, I had the exact issues you you’re having. I had my trans in and out 4-5 times this year. I had the plastic alignment tool and tried having my wife push the clutch in, I lifted up on the tool while tightening up the pressure plate.....nothing worked, other than bolting it up with a ratchet and then the disc will move in to place.
I purchased this alignment tool from Crash at MCACN last year and what a difference that made.....the trans slides right in to place with no issues!
In other words, try and find an old input shaft for an alignment tool.
Kurt
