Input shaft to pilot bushing alignment

I am trying to put my transmision back into my TR7, and having a heck of
a time with it. I used a clutch alignment tool, and double checked that 
it slides in easily. I don't even feel the pilot bush when inserting it,
so it seems to be somewhat aligned. :) The problem comes with trying to 
mate the transmission to the engine. (in the car) I have the splines 
enguaged, slightly, but the I am having a hard time sliding it the last
inch or so. With one person helping, both of us pushing (HARD), it moved 
the last half inch or so. (slowly; it still needs another inch or so) 
I noticed before I put the transmission under the car, that the pilot bushing
(actually a needle bearing) is only about half of the depth of the hole it
is pressed into. (it is flush)

What I am wondering is: Might I be pressing the pilot bushing deeper into
its hole, or is there a land (ledge) inside that acts as a positive stop
to prevent this from happening? 

I am most of the way there, and would prefer not to have to take it apart to
check, as it took _many_ hours to get it where it is, and I really need to
get it back on the road. (it's my only licensed/insured/close-to-driveable car)
I have read you have to mate the engine and transmission outside of the car,
and drop them in as an assembly. I really don't see why, as it is common
procedure (with other cars) to reinstall the transmission with the engine
in the car. Why would this one be any different?

I appreciate any help anyone can give me.

Thanks,
Kevin

P.S. I have a couple of long bolts going through the bellhousing and the
     engine's back plate (what's it called?) to help align them. It does
     help a lot, but maybe not enough.
