Look immense dude.
There's a few peeps around here who are after them too. Maybe you wanna have a look in the Wanted section and help them out?
Trust me they are like rockin horse poop to find. They were a regular item on German eBay last year, but even on there, there hasn't been any for a long time.
There were a few sets of 19" detroits/huffs (black monza's) on eBay.de, but I am not sure if they are the Chinese ones.
