Looking for a main frame for a track build if anyone knows of one for sale anywhere? Can be a salvage frame, imported, blank from the factory race frame, but ideally needs to be straight and not missing large sections like the one on eBay for $4000 think a streetfighter frame will also work. It’s the later frame I’m after with the cut outs on the side like the one in the picture below. Part number: 47023223AA
