Trouble Installing 18 spline A-833 through dual disc clutch assy.

I have to say that this was my very same problem with my car. I was going to put the transmission on the engine and then I would slide it in.
Well first off after a bunch of different way to do it I called the company McLeon for info on this. I tell you that they really helped me a bunch on this BUT it still will not go in. So finally they said to send it back. Well when they called me they were very good about this and told me that the fingers on the clutch were the wrong one. So now I'm finally going to get my trans on to the engine. NOT. No way. It was just as it was before. Now I getting torn up on this thing. So I told them that I m going to ship it back for look at it. Well they called and said that it was all perfect. So I put in and again and its the same. So I used 4 longer bolts that hold the trans in place and when it got to where it was tight I put in the bolts, and very carefully was able to actually draw the trans into place. At that point I had put in the engine and got it running. When I had for the first time I had pressed on the clutch pedal and it was like butter. It is still in there.
When I have thought about this and my thought are that it has to be in the part that they give you on this. When I have to remove this thing I will make a one out of a piece of wood.
