did you use the plastic clutch alignment tool included in your clutch kit?... if so that might be your problem... those have too much slack in them and will allow you to tighten everything down in the wrong position... I didn't have a steel alignment tool around so what I ended up doing was leave the inspection cover off then label the pressure plate bolts in their torque sequence, loosen the pressure plate up just enough to where you can move the disc(s) around without them falling... then have someone at the other end pushing the torque tube while you spin the disc(s) to get them lined up... after it is fully seated you can start torquing you pressure plate bolts, you will need a flywheel turner since you will only be able to get to the bolts near the bottom of the inspection cover

This is how i did mine.
I had the torque tube apart so I pulled off the front of the drive shaft to use as a clutch alignment tool. I have heard this can get better alignment then a plastic part. It was a bit of a pain relative to the fact that I have a twin disc so its lots of stuff to line up.
Once i did all that i put the bellhousing together and the drive shaft together and installed the torque tube seperate from the trans. When I did that the wires that run along the torque tube where constantly in the way and tring to get wedged between the bellhousing and the torque tube until i figured out how to keep them out of the way while bench pressing the torque tube and wiggling it around, and then it just fell right into place.
Big pita alone on my back in my garage, but those were the 2 things i did to get it done.
GOOD LUCK!

I used the alignment tool and just bolted it up without too much issue. The key was to make sure the TT was level to the back of the engine and pay close attention to the splines so they engage correctly. It won't engage for s**t if the TT is angled up or down.

I used the plastic alignment tool and then I put the Torque Tube on the bell housing without the TRANS/DIFF installed.
You will be amazed at how much easier it is to install the TT into the clutch when there's NO weight on it!
Its a LOT easier to install the Trans/Diff on the rear of the TT than having to deal with the entire assembly.
I installed the entire thing my self on my back with the car on jack stands.
I have a SPEC Duel Disk Clutch and its VERY VERY easy to bend/warp the clutch disk/s if you accidently let the entire drive train hang when the torque tube shaft isn't fully bolted to the bell housing.

Loosen the pressure plate fasteners and then install the alignment tool. Slowly tighten the pressure plate bolts and at the same time keep wiggling the alignment tool so that its perfectly aligned and slides in and out easily.

I had no problem with alignment on my dual-disk Mantic. I used the plastic alignment tool that came with the clutch kit. As others here have mentioned, it's important to make sure you have the TT level with the engine so the tip of the shaft lines up with the pilot bearing. If that's good, the splines should slide in easily.
I install the TT/tranny/diff as a unit.

times like 3. It's the easiest way to prevent mucking up the bearing too, IMHO.
