Clearly the initial issue will be removal of the springs & rods which should still be possible with a generic fork suspension assembly tool.
My own opinion concerning remanufactured parts is - as ever! - that Innocenti were extremely good at what they manufactured, from design, material choice, quality control etc & there are a large percentage of those OEM components that have never been bettered, like for like. If you think about why anybody sets up to remanufacture Lambretta bits, there will always be the main principle of the profit motive & whilst new, shiny parts can look great, it’s what you don’t see that will often cause a problem. Your spring rods will certainly have failed due to the manufacturer’s choice of material & heat treatment - if any - & absence of certified quality control.
Here in the UK -as many nations will attest - we have a tendency to complain to the wrong people which means good standards are not applied or adhered to. In certain instances you can factor in a manufacturer’s belief that they ‘know better’ as was witnessed with rear hub bearings (failing plastic ball cages) & front sprocket drive bolts (too long so they bottomed out & allowed the cush cam to over-ride cam on the sprocket)
