Transmission Filter part number?

I was trying to change the automatic transmission filter in the 70 Dart, with the slant 6. I ran into a problem;the filter that the surrounding parts stores all are trying to sell me does not match the filter in the car. The filter kit that Autozone, O'Reilly want to sell me the filter only has 1 hole and is much bigger. The filter in the car smaller and it has 2 holes.
The part number Autozone sold me is a Duralast FT127. It had the correct pan gasket (14 bolt).

What is the part number of the correct filter?
Thank you,
Matt
