Farmall Cub

I am ordering all the parts to convert my cub to 12v. Can anyone tell me the part number for the proper blocking diode that goes to the "L" terminal on the alternator?

Thanks.

Wiring diagram #5, list of parts has a diode part number.

If you use a single wire alternator, diode not needed.

I ordered the Hitachi alternator. I don't think it's a one wire setup.

Another diode listed in the wiring diagram.
