The Logic Off Topic list

Hi

For the last 4 hours I've been trying to find the jam pack 4 software 
instruments that I'm using in garage band 2 in logic 7.1
The logic literature leads me to believe this is possible,  but I 
haven't been successful.
I've created an audio instrument track in the arrange window then in 
the track mixer under   I/O I select stereo/ AU instruments/ logic/ 
garage band instruments but jam pack 4 does not appear.
I have no trouble playing jam pack instruments in garage band.
I've tried importing my garage band file (with jam pack instruments) 
into L7 and tried dropping my jam pack instrument files into the L7 
arrange window but the apple " file/find "
can't locate either.
Am I trying to go where no man has gone before?
Anyone have any tips?

Too many questions
Too much time
