Hi I had the bright idea to remove the six tail light lenses in my Countach. As everything else in the Countach, a very simple task can become quite complex. Three of the 12 little 7mm nuts were rusted and impossible to loosen (even after 24 hrs soaking in WD40). Very carefully, with a mini hack saw blade I was able to remove them without damaging the rear of plastic light panel. Now I will have replacements machined from billet. Should have them by Friday - will post pictures. When I bought my car the back light assemblies were not completely waterproof - hence the rust. I was extremely careful in the disassembly because Lamborghini no longer has the red reflective panes of the Euro model. I cleaned the light sockets which were oxidized and will replace the bulbs with new ones. The lenses and inside of the lights were cleaned and look brand new now.
