Hello Andreas, Yes it is very rare but u still can find parts in other countries, I saw one in Australia but without the cooler.I know there is a cooler in the back compartment. I have the same car like you and fully restored. It went to car shows already twice and i got trophy from it. Is your cooler still working? I am residing in the Philipiines and maybe can help you find some of the parts you're looking for. Goodluck! Glenn
