I have shipped parts from Ireland to Australia, NZ, sent a new Alfa 147 centre console, with tracking and insurance, arrived in 3 weeks, cost 75 euro in postage, its all going to depend on KG weight off the parts sent, and size, anything over 6 foot in length impossible to send I find,
I have sent fiat punto mk1 gearshift gators to Australia and they cost just 28 euro to ship with tracking and insurance.
But at moment with COVID crises would not even attempt to send past the UK from Ireland, as parts end up stuck in Heathrow airport storage facility.
