Torque Converter fitment question

I'm looking at a replacement transmission for my 72 Dart 318 - 904.
I already bought a torque converter -

It shows fitment for Darts from 71-76

The transmission I'm looking at is 74-75 PK3743423 which means it could be from basically anything with a 318 in 74-75. Seller says it came out of a 73 Duster.

My question is:
Is the torque converter fitment based on the transmission or the model of the car? Or put another way, will this torque converter work for any 904 from 71-76 as long as it goes in my Dart?
