Thank you very much guys, for the links!
I've seen these wheels on ebay allready, but actually i'm not a realy big fan of those spoke wheels.
I'll contact this guy from australia, sellling those repro bumpers, they look pritty good to me.
As my actual project is so less used, i will keep this one on my shelf and may look for another roller for some vintage racing, as i realy want to drive one of these cars...
