52PU,
How far you going? if it's more'n a hundred miles I 'd think about full trailer or flat bed.
How long has it been sitting?
Definitely change or at least top-up the tranny & rear-end oils.
If it's been static for long while, I'd at least get some gear lube on the front U-joint and its bushing- some three-speeds had a hex-head pipe plug on the extension housing: this was for lube at installation- either dump some gear oil in there, or split the drive shaft "ball" and saturate that u-joint good.
If you open up the torque tube, might as well remove the u-joint entirely for the tow.
There's a lot of unknowns here; I've had brake return springs break and cause wheels to lock up;
I'd want to be sure everything was loose & free before setting out on a "tow".
It's winter too; bad time to be on the roadside with a problem.
Now, when i wuz 17, I'd just back the '54 3600 up to the new toy, clamp on the tow bar, and away we'd go, dry rotted tires & all!
Didn't never kill nobody that way, but I was lucky!
I think I'd approach things more conservatively, now-a-days!
Just my 2....(there's no "cents" key on this thing!) worth.
