Not seen that before, but it looks like it has been squeezed to fix it into position. If that is the case, it is not re-usable.
Need a workshop manual to describe how the new one gets squeezed, as will probably need quite a bit of pressure. Pugglt Auld Jock have you seen this before?
The workshop manual and the parts catalogue show the cross grooved spacer held on with a circlip, so the spacer should just pull off by hand. The manual doesn't specify any special tool required to pull it off.

Yes, and so I tried. The circlip came off easily but the spacer wouldn't budge .. not even with a gentle hammer tap. Today I'll try a little bit more force.
Nope. Believe it or not, I've not yet had to take any of our Fiat gearboxes to pieces. In fact it's been about 15 years since I did anything more than seals and linkages on any box! Lucky me!
Hi Karlton. Glad to see you solved the problem and I congratulate you on tackling this job - brave man! I'm not at all familiar with your model (where Fiats are concerned it's mostly FWD Pandas and Puntos for me - although I did help a friend who owned a 131 Mirafiore and another who had a classic rear engined 500). A lot of the older cars I used to work on for a living - Morris, Austin, Hillman, Vauxhall, etc, etc with rear wheel drive had gearboxes very similar in concept to this from what I can see in your images. They pretty much all had prop shafts with metal universal joints not the donut your's has. Although my Imps had them on the driveshafts to the wheels as did the FWD Triumph 1300 (not a good idea - too much torque used to destroy them quite regularly). I'm struggling to understand why you have that spacer and rubber on the shaft at all - what does it do? why is it there? does it engage with a "socket" on the driven shaft?
