Anyone have any idea what motor may be in this Land Cruiser? The previous owner put it in from another Land Cruiser, but I'm not sure which year. How do I tell if it a 2F or F? Also, on the front end picture, what is the second alternator looking pulley on the lower right side of the belts? The truck is not at my house, so I can't get any other pics. Any info would be appreciated. Thank you.
