Will a '73 Continental Mark IV tranny fit into a '74 Swinger with a 318?

Hi,
Recently purchased an almost "all original" '74 Swinger with a "numbers matching 318" from FL.
Paint and air cleaner are definitely NOT original. Ad does not say that it is the original trans.
In the trunk, in a small box, found a receipt dated 5/2023 for a rebuilt transmission from a '73 Continental Mark IV, from a trans. repair shop in CA.
Could this transmission fit a 74 Dart swinger with a 318?
Please tell me no.
