Where to get manuals for Bluebirds?

[transit360]

I'm trying to find some manuals, either books or CD's, for
Bluebird. I have two '98 Bluebird QBRE (Rear engine Cummins Q-bus)
that were airport shuttle buses for National/Alamo. I DESPERATELY need
manuals for these things as this is the 1st Bluebird(s) I've ever
owned. Please help! I've called my Bluebird parts distributor National
Bus Sales and they're not sure where I can get them, either.
Suggestions?
