I ordered these from a German Supplier and had intended to use on my 1969 bmw 2002 only to find that the original ones cleaned up good enough.  I also found new hardware to go with these so I am including 4 - 8mm x 25mm yellow zinc bolts and washers.  Before installing these you might want to get some larger fender washers to be used with the standard washers.

Please note the elongated slot and the "captive" nuts that allow for fine-tuning how the bumper attaches to your car.
