Help identify my Converter

1) was/is the plan.

My initial intentions were to collect info on the converter in my continued attempt to learn the most info possible about my car.

TRANSMAN's comment made me a bit nervous though. "If this is a used converter, and you don't know the history of it, DON'T use it. As others have stated in many posts, a used converter makes a great door stop."

Possibility that if somethings wrong, it could damage my motor, trans?

Anything is possible with a used converter.
If it were me, I would probably have it flushed out and see what it does just for the fun of it. (but I could fix it if it messed something up)
It's also a lot easier said than done to "Buy a new one" like a lot of people here say to do.

I still say you have two choices.
