GAWDDD!!!!! NO!!!

howdy..
as my neighbor and i were removing the transmission
out of my 66....
he noticed the starter..and said that the tranny wasn't a c-4 cause there were only 2 holes for the starter to go into
and he said a c-4 has 3 holes for the starter.
Now..is he right or wrong?
It seems irrelavant..but it keeps nagging at me.
and if so..what else could it be?
i think he should lay off the sauce..
thanks...
