Have 2 problems on the NB. Dzm + roof

Hello, I bought a 02/2000 NB, with 103kw and have 2 problems. Problem No1. Reversing speed meter does not work, it stands on zero. Problem No2. Deck locks are probably not so good anymore, I can open the roof without pressing the buttons. Can someone send me a link to order from these locks? Problem No.3. I am looking for rear lights and no clear glass but I just can’t find anything. I would also take those from the NBFL, but I don’t know. whether they fit and where I get them cheap. Thanks Andy
