if i remember correctly, the '78 air box has all of the convoluted intake
and emissions plumbing at the front of the box.  one modification that used
to be common was to find a front cover from an earlier spica and use it
instead.  the earlier boxes had a front cover that had one single input that
went towards the front (cold air intake).

this is a mildly effective mod, if i remember correctly.  make sure that
when you modify your front cover that you direct cold air into the box.  a
bigger input that is sucking in warm air from the engine compartment will
not be as effective as it should.

good luck,
