I'm sure that the one at Amazon will fit.

According to the 1980 Parts Manual, the final issue for the 60 series Patrol, the starter motor part # is 23300-C0600, and that matches the description of the one in Amazon. It's totally interchangeable with the one you have, although it looks completely different. I used to have a 74 Patrol with that starter.

The price is really good.
