name this wheel.... oz racing somethings haha

i am looking for the name of these rims. they are long discontinued. i was told they are oz racings. they LOOK kinda like kmc units. but are not. here are the only pics i have. one is obviously with the center cap and one is without...  also whats the best place for finding center caps that are out of date like this. here are the pics. thanks   on the black truck in the front of this pic...

I dont think those are Oz's but can not be positive...sorry

Those are Niche Sideburns

they are niche. dude just sent me a pic of one of the center caps. and it had the "N" symbol. douche thought it was a z.... thanks a million. love this site. i can show a 1912 rim and someone will know what it is. thanks again.
