If the top picture is what you have in the car, the fluid drive coupling is there. The transmission in the bed is a standard 3 speed, not hydrive. The bell housing looks to be for a standard clutch so it is safe to assume the 3 speed trans next to it has the short input shaft and can't be used with the fluid drive coupling in the top picture. Also, my Wayfarer uses the "stubby" transmission (shorter than yours shown) so you my need to shorten your driveshaft. If you move the 3 speed and standard clutch to a FD engine, some machining may be necessary to make the starter engage the flywheel ring gear correctly because of the above mentioned thicker crank flange. The late Don Coatney did a write up on this with pictures. Hope this helps....
