Sorry to hear about your slight problem. Mine snapped in Ghana due to severe overloading, I managed another 200 km (gently) before they were replaced.
Are you sure it’s worth shipping genuine parts from Europe?
Before leaving for WA in 2003 I investigated the replacement of my (already tired) rear spring packs, or the possibility of carrying a spare. At over 300 euros a pack (!!) I decided to take the risk and get an African repair if needed.
Very glad I did, the garage I found in Accra sourced a set of Mercedes springs, had the eyes adjusted for my spring length and I got a bit of a lift too. (the rear eye was put above the spring gaining me about 10 cm)
All for ¼ of the European price.
The spring packs are really heavy, too. It took two mechanics to manoeuvre it. DHL could be costly.
It’s not necessary to stay on Iveco genuine parts if you replace both sides.
The spring blades are a very standard width; ask around there must be a friendly blacksmith who would be prepared to adapt a local product for you.
Check your mail.
