Here is a link to photos of the OEM and mods to the replacement.

Two of the pins are labeled + (positive) and - (Negative). Orient the original and replacement rectifiers so those pins are in the same position. Note the ones that need to be twisted to match the original.

In this photo, the original (OEM) is on the left. A new one is in the center, and a new one modified with twisted pins is on the right.

You can buy this from any electronic distributor for about $2.50 each. I'm kinda partial to DigiKey because of the fast & inexpensive shipping. Get one rated at 25 Amps and 1000 volts. The high voltage rating may save the replacement next time the generator is shut down under load.
