Alternator mounting

[PARTSCHEV]

I have a 1967 malibu 327 auto no ac
the gm assembly manual shows the upper mounting bracket on the rear of the alternator ear and the bolt, washer, and lock washer going from the rear of the ear.
my car has the mount bkt in the front of the alternator ear and the bolt and lock washer going in from the front of the ear.
which is correct?

any help would be appreciated,
thanks,
mark
