Tiny Bit of Metal Flake in Differential Fluid

Can't find the info. However, it turns out that different gear lubes will not always protect certain parts, and perform in the ways we intend. I'd clean it out, and put 600W back in it.

Fluids that suddenly have chemical properties changes can cause leaks. And once they start leaking you might slow them down a little, but they always will leak.
 
Go on youtube and enter corn head grease. There are some good videos showing how the grease flows during drive system operations. It is impressive to see how uniform the flow of grease is when lubricating gears and bearings. John Deere recommends and uses this grease in many of their drive systems. In my opinion this grease out performs the 600W oil available through the parts suppliers.
 
Originally, there was no gasket between the torque tube & differential housing. In 1932 & subsequent years, the B-4507 Gasket was incorporated. Why? Because the joint leaked! The B-4507 Gasket fits the Model A, so suppliers include it in their parts for the Model A and it is necessary. If your Model A does not have this gasket, drain the differential, remove the bolts connecting the torque tube to the differential, cut the gasket at 12 O'clock and slip it into the joint with some sealer.

Did you check: started leaking (around the torque tube connection)

I’ve torqued the banjo bolts for the trumpets a number of times since I’ve owned the car, but I never really thought about the torque tube bolts, especially since they were safety wired.

I wasn’t able to get a good bite on the safety wired bolts to check the torque. So, I found some safety wire pliers at Harbor Freight, removed the safety wire, torqued the 6 torque tube bolts (it turns out they were not as snug as they should have been), re-safety wired the bolts. It’s been a few days, and I don’t see a recurring leak. Maybe this is fixed.

That is an excellent idea.

IF you can get the torque tube apart from the banjo to slide a gasket between them , one slit probably won’t get it by the two pinion nuts, maybe two cuts at 10&2 would get by the pinion nuts. My shade tree temporary would be clean the joint with brake clean blow dry smear some black RTV around the joint. Remove a bolt spray brake clean in the hole, blow dry with compressed air, coat the bolt threads with RTV , reinstall the bolt, continue with the other bolts . One bolt at a time ! wouldn’t want to cause issues get the torque tube out of alignment with the banjo .
