Had seen the relatively common Ness covers and the new pieces from Mother Harley. The OE for those has both a chrome and the black pieces Harley still only offers. Had also seen and really like the "Yafterburner" pieces from Yaffe. Have those on the Road King project so couldn't use them again on another bike in the same garage. That would be oh so gauche.
Hadn't seen these until a week ago though. From a company called SMT Machining. When I ordered they only had black pieces in stock. They pulled a black set out of inventory then stripped them and had them chromed. Still had them here in about ten days. Very pleasant folks to buy from and the parts are nice. They're going on the old SERG sometime sooner rather than later.
