The drum nut socket should be 29mm pre74 but it would be a castle nut.
Yours look like post 75 and should be 30 or 32mm (not sure but a size up than before).
I agree with Mark that your yolk is pre 74.
Driveline bolts, nuts and studs are 10mm before 74, and 11mm after... You may have a mismatch here!!!
Entreaxe between the bolts would be different also, that may be why they removed a stud...
Otherwise bolt, lock washer (yes don't forget them) and nuts for driveline are available at Toyota for ~1$ a piece, for pre and post 74.
Studs I don't know.
