Transmission Numbers

I can't find that specific number, the 3410...-. series is typically of the year 1970.

If that helps.

Yea, thats what it looks like from the link to the trans guide 73duster posted. Weird thing is is the number 73 is in front (towards the engine) of the boxes.

Here are some pics from the driver side of the transmission.
