I've noticed similar sounds from the differential in my '77 MGB. I
worried a lot about it for a year, worried a little less for the next
year and ignored it for the next three years. It's still running fine
although it's annoying. I found that a heavy blanket laid across the
deck area that the top folds down into helps a lot (and the blanket can
be useful for impromptu picnics as well!) I think that putting one of
those plastic battery holders in would help reduce the sound further
by preventing road and diff noise from coming in through the battery
compartment.
