HSN/TSN

Hello municipality, I unfortunately drove off the right exterior mirror at my Womo. Apparently it is not so hard to replace the mirror with housing completely…if you have the right spare part. It is a mirror with a long arm. Unfortunately I can not cope with the input of the HSN and TSN. I do not know any other information. What do I have for in model? An Eura motorhome is not listed here. What do I have for a “platform”?? Which model do I have? The HSN mu ß 4 digits that have TSN only 3 digits. In the car bill stands -under D1 (brand): Eura Mobil -2.1 (code to (2)): 1727 -2.2 (code to D.2 with test number): 00000000 -J (vehicle class) : M1 -4 (type of bodywork) : SA -E (vehicle identification number): ZFA25000002D90849 -3 (test number to vehicle identification number): 3 -D.1 (brand): Eura Mobil -D.2 (type, variant, version) : 131 -D.2 (type, variant, version) : FBM8 -D.2 (type, variant, version) : AAAC -D.3 (trade name) : PT720 QB -P.1 (hub space) : 2287 -P.2/P.4 (type, variant, version) : FBM8 -D.2 (type, variant, version) : AAAC -D.3 (trade name) : PT720 QB -P.1 (hub space) : 2287 -P.2/P.4 ( Nominal power KW be Nominal speed): 110/3600 What do I have to enter with HSN and TSN? In normal vehicles it is a child’s play to order spare parts, but here? Maybe someone who knows how can help me. Thank you.
