If you already have the correct connector, they you may as well purchase an NOS sender.
Mine is probably more suited to someone whose connector was cut off and thrown away years ago. Almost all the replacement ones had either a threaded post, a spade or a disc on them, and when installed, the installer cut off the connector and crimped on a spade connector or whatever fit the new sender.
