'87 Tercel, no pilot bearing?

I am replacing the clutch on an '87 Tercel sedan with a 1.5 liter 4 cyl and
5 speed manual transmission.  The car was purchased new and this is the
first time the trans has been out of it.  Before beginning, I ordered in a
new clutch kit consisting of the friction disc, pressure plate, throwout
bearing and pilot bearing.   The kit comes with two pilot bearings and one
pilot bushing so that it can fit a variety of applications.

I was a little surprised when I removed the tranny and found no pilot
bearing in the crank at all and no journal extending past the splines on the
trans input shaft that would ride in it.  This car has always had smooth
clutch operation with no shuddering, vibration, etc.   I was just curious as
to how common this missing pilot is?

In general, it is common for transaxle designs to dispense with the
pilot support, as the shaft is supported nearby behind the release
snout.  The multiple parts you received are probably for non-Toyota
applications that use the same clutch plate and pressure plate, but
that's just a guess.  Maybe it's easier for them to throw several in
there rather than pay for the correct part to be selected for each
application.  If there is no pilot tip on your input shaft, as with
the Tercel transaxles, then there can be no bearing in the crank or
(flywheel).
