ID this part. 74 Dart Sport

I have a 74 Dart Sport 360 and have been doing a lot of work, planning on rebuilding the clutch pedal linkage it's a bit screwed up. The plate I have attached to my bellhousing is the same as this picture, is this correct for an a body? I can't find anything online except for this one photo, non of the repo stuff has the extra flange on the side.
