your best bet is to call the seller and ask.  they know more about all
the foreign variants than i do.  but all b2's should be interchangeable
for all models that use them.

to answer your other question, the b1 was in the std hatchback - the
basic model.  the b2, the one you want, should be real common and cheap.

one more thing - if you're in california, i believe you need not worry
about what used to be california emissions on this vehicle.  according
to my local smog guy, and he showed me the page in the dmv handbook that
they use, the egr system that used to be mandatory on ca automatics,
"need not be present on the vehicle".  i believe this is because the law
for ca not accepting 49-state emissions vehicles has been overturned, so
now, what used to be out of state emissions are legal in ca.  that means
you can dispense with that hideously unreliable egr system completely
and use a 40-state ecu.  that's what i have on my 89 civic ca auto and
it improves driveability immensely - all for $30.  buyer beware, i have
not yet smogged this vehicle in this condition, but as i say, i've seen
the page in the dmv handbook - check with your local smog guy to be 100%
certain.
