That's a 1980 or later FMX.
Dipstick tube hole in the case?

Transmission is E0AP
That transmission has the 1964 and earlier FE bellhousing, for the long shaft starter.
Jack the hindend of the vehicle up and keep the engine level...
Late to the party but I'll add my bit.
It seems a bit silly to add subframe connectors to a Ford unibody without welding them the entire length of floor from one end to the other. The amount of stiffness added compared to just welding, or God forbid, bolting tubing to each end of the subframes is huge.
I usually cut the floor open the entire length of the connector and weld the tubing the entire length and around the front and rear stubs, and reinforce the factory welds and stubs as necessary. If you're going to do it, make it work. I you're worried about cutting your precious car, well...
In 1997, I built a 1964 Falcon Sprint for a daily driver/commuter car. My daily commute included 37 miles of twisty mountain roads through a National Forest. While I had the 2 strips of floor cut out and was fitting the tubing for the connectors, I had a couple of friends stop by and tell me this was WAY overkill for a "driver". Probably so, or so I thought.
About 6 months after I started driving the car I was sitting at a traffic signal and was hit by a raised Ford F250 travelling about 70mph. The car was demolished but the floor never buckled at all. After a lengthy hospital stay and then an inspection of the car I am confident that I'm typing this post at least partially because the entire floor was reinforced.
