Ford used a couple of different starters. Some were regular Ford starters
and some were Prestolite and they were reverse rotation .Most of them
top mounted in the bellhousing . Auto Electric shop that rebuilds starters
in your area should be able to help you .If its the standard Ford starter auto parts
store should have it like Napa . I think the Prestolite drive may be different , someone
else here may be able to help you that knows Ford better.
