I recently stumbled on the fact that
there is another option for a Diff for your Tiger.
**NOTE, I have NOT laid hands on this device, yet.
SO, I'm just going by what is seen and heard...**
The GREAT news is it goes RIGHT into the Tiger
WITH the original 19 spline axle shafts!:

Also, note, the link picture shows 2 different bolt patterns, 3/8 and 7/16??
HOWEVER there is an issue!
As it comes out of the box,
IT WILL NOT WORK in your Tiger!
AND, Currently, If you mention
Sunbeam Tiger, they will not sell it to you!
...even though it has the Tiger listed in the applications.
They have had at least one Tiger person install
it in a Tiger and found a problem!
And the Seller could not suggest a viable FIX.
What is wrong with it?
It is not complete for Tiger use.
This is NOT the same as saying it
will not FIT.
It will go right into your Tiger rear
axle housing.
BUT, it also needs a SPACER installed
between the axle shafts in the center of the Diff.
This is the same issue with a Torsen and Tru-Trac.
The stock Tiger Diff has a captive spacer
that is held in place with the spider gear cross shaft.
The Power-Loc also has a spacer, commonly called
"Buttons"
The reason for the spacer is to transfer side forces
from one axle shaft to the other.
The tapered axle shaft bearing only takes side force from one side.
So the side force from the other side NEEDS to be transferred
from the OTHER axle shaft, THROUGH a spacer.
Some years ago, I remade the spacer in Tom Sakai's Race Tiger
to keep it centered so it cannot touch the side gear splines.
It has TITS that go into the center drilled holes of the axle ends:
