I'd look for the fan being loose on the shaft; then for a fan blade fouling
on a bolt or the case.  It might be something inside the alternator, but
that usually is more of a grinding noise than a clang.

The fan fouling might be a symptom of bearings that are starting to fail and
have allowed the shaft to move.  Or it might have simply gotten bent
somehow.

BTW, the 78-80 Ford Fiesta came with two different alternators.  Be sure you
get the Bosch one (found on cars with AC or heavy duty electrical), as the
Motorcraft ones take different mounts and connector.  But I agree with Joe,
the Bosch unit is much better than the stock Lucas, and likely less
expensive to boot.
