Diode Part numbers

[tropical]

Does anyone know the part number for the diodes that sit right behind the alternator fuses in the front engine compartment? These diodes screw into a large heatsink. They have a shaft with a hole for a screw and the bottom looks fit a 1/2 inch socket. I have one that has a broke shaft and need to replace it. We have a large electronics store here in Orlando and I would like to match it up.

The book says it's a 70 amp diode. If I read the wiring diagram correctly they are the diodes for the alternator out lights.

Yes the book does not show the part number, they want you to buy the whole assy at a high cost.
If you take the diode assy off the plane and take out the diode it will have a p/n on it, if you could let me have that number I can convert it to a more modern one as that diode is not available any more.
