Hi,We are having trouble finding a right sized wheel hub assembly for our prototype and this picture might be able to work. However, I would to know what size does this wheel bolt pattern has and other general dimension. If you have other parts that maybe fairly similar this this, we would be interested in checking those out as well. We are hoping to find a flange that has three or fout bolt holes that is bolted from the outside of the car with any size four bolt wheel pattern as long as the diameter is less than 144.3mm. Thanks.
