I'm a regular participant on Reddit and someone there had a question about the procedure to do a brake job on the rear drum brakes on a 2001 Lancia Ypsilon which is on the same platform as the Fiat Punto.
The question was: Does the axle nut need to be removed to change the shoes? Initially, I thought it had to be because of how our Mirage rear brakes are configured.
I was surprised to learn that while similar to the Mirage in concept, the configuration is completely different underneath the drum and a better design than the Mirage in that the drums are less expensive because the Lancia Ypsilon \ Fiat Punto have a hub that spins on the axle spindle and the drum fits onto the hub instead of having the hub built into the drum like the 2014/2015 Mirages have.
What's also fascinating with the Fiat design is that the lugs and lug nuts are one piece! Not sure if that's a good thing but I've never seen this before. The mechanic used a 3970 Liqui Moly spray to prevent the drum from sticking to the hub. Didn't know about this product. Great stuff.
