1954 3100 235 3 speed manual

Tried search function with no luck but here goes.
New owner here and have been going through truck fixing things here and there.
I have the shop manual but is not clear enough for me to understand the connection between transmission and driveshaft. Went to change tranny oil and found it very low, noticed small drops after filling and continues to seep slowly while in garage so wondering if any videos out there about the shims and seal on where to start.

For some more background after a 50 minute drive I picked up a nail that was unnoticed until next day when came out to flat tire, axle seemed to leak decent amount with the truck tilted that direction and axle vent was clogged so cleaned that out and hasn’t leak there since, also checked diff levels couple times after driving with new tranny fluid so I THINK it is not leaking past to overfill diff and maybe that occurrence was freak series of events but I am no expert......but the collar slow leak remains

Other things on list for another day is oil leaks enough on flywheel to see line of throwing vaporized oil if parked idling, drips what I assume is normal-ish for these trucks leaning towards heavier side but after maybe 100-200 miles haven’t had to add oil yet

Also need to find flywheel cover! Maybe that helps leak a tad bit less spray?
