Proof of admissibility !!!

Moin Moin !!! I worked out a 99 Road King Classik 96 inch and had to go to the TÜV !!! And the honorable gentleman wants for footrests , handlebars (16″Fat Abe ) and tires (Dunlop 402F front and 402 back) have certified the admissibility !!! My question : Do I get these at a dealer or how does something like this work ?? And can I not stick the badge on me because of a worn engine storage ??? The Lord God in Green Kittel has it quite well after me !!! I hope to your answers and stay with friendly greeting !!! So long, Texas
