As DW says, that doesn't quite add up.
I'd suggest the bearing wasn't fitted correctly and allowed the shaft to come out. As the splines have left the diff, you lost all drive
(and you'd get a racket from the engine/transmission). Then you've tries towing and the shaft has come out completely.
The only way the shaft can do that is if the retaining collar isn't fitted correctly or the bearing retaining cover bolts come out.
Fix the shaft first and get someone to check what you've done. Then ifthere's still no drive look at the engine.
+1 fix one problem at a time and the biggest one now is the back axel!!
Once that sorted try another run
If same as before double check that nothing is restricting the movement of the shifter set up.
Its not important how far the stick moves )that will vary dependant on your set up) but it needs to be unrestricted and move the gearbox end to the
limit of the gearbox selector mech.
If still no good, for he effort I'd look at swapping the whole engine first to save building (re-building) anbdy new faults in, plus you'l
know the condition then rather than waiting for the day and finding they're scrap anyway when you need one mid summer

Thanks again everyone. Yes 40inch, that's exactly what mine sounds like now. Perhaps the engines ok after all!
With regards to the half shaft and bearing, it was 100% correct, the bearing and retaining and hub plate nuts were all spot on! However, on examining
the shaft splines tonight, they've been stripped bare almost, so I'll need a new one of those. While I'm taking the axle to pieces
to clean it of any metal particles, are there any worthwhile jobs doing while I'm at it?
Presumably, if the splines wore and jammed, that'd be enough for the shaft to be spat out of the bearing?
Are half shafts available brand new? I have stumbled across a few axle/diff rebuild kits on the tinterweb too, should I give one of these a go?

Has the retaining ring come off then to let the shaft out? I wouldn't imagine the stripping of splines could create enough force to push it of.
After all it should be tight enough to hold the shaft in the bearing under cornering forces.
Photos would help.

I'd have thought exactly the same to be honest.
I'll get some pictures tomorrow evening

As said by many, somethings not right there on the axle. If the half shaft has come out with the bearing still on the shaft, then the retaining plate
on the axle end isn't fitted. It's impossible to come out otherwise. If the axle has had a disc conversion then normally a spacer plate is
supplied to replace the drum back plate thickness, if that's been fitted on it's own without the bearing retaining plate then that's
why the bearing has come out....there's nothing holding it in!.
If on the other had the bearing is still in the axle, then the locking ring wasn't fitted behind the bearing on the half shaft or it
wasn't tight.
A couple of pictures will enable a quick diagnosis of the axle problem.

Below are some pictures.
I'm taking the rear axle out anyway to give the internals a look over to make sure there's no damage.
Do the splines on the shaft look reusable I.e is there enough depth to them?
From the picture of the hub, you can see the retaining collar left inside, with it's ribbed inner surface and the shaft has a slightly ribbed
texture too.

Ok, the bearings stayed in the axle and the halfshaft has slipped out of the bearing and retaining collar. The halfshaft looks to have some damage in
the bearing and retainer area (perhaps from a previous bearing change some time in it's life) which could quite easily lead to the retainer ring
not being as tight a fit as it should be. Along with a bit of damage on the splines, i would swap both shafts and then you know it's right.
