The stock tanks are thin and tend to crack and leak from metal fatigue due to turbulence in the papercrete, and road bounce. The seam around the bottom will separate from the side, too. The plywood stiffens it a lot, especially if the tank is glued to the plywood. The other half of the plywood makes a nice lid.
If your tank is fairly thick with welded ends then flexing might not be a problem.
The yoke where the universal connects is usually larger than the body of the differential and removing it is fairly involved. To fit plywood over mine I had to oversize the hole and then fill in with bondo. Also, the case had ribs on the outside that required matching slots in the plywood and tank bottom, hard to get a tight fit. The case of my differential seems to be cast iron, which is hard to weld to. If you could do it, you would eliminate that potential leak. It sounds like you have what you need to make a good heavy duty mixer.
