904 floor shift conversion?

I know they were a lot more plentiful in the late '70s. But the old Mustang floor shifters were pretty decent for swaps. My one and only experience with a ratchet shifter from a well known manufacture was a pain in the backside. It was a "fiddle with it constantly" affair. Of course I date myself, ratchet shifters were kinda new on the scene at the time.
