Well point taken, but if your Going to go through all that trouble casting your own lighs you can find a material like this creativesafetysupply.com/Ref-Spray. And For safety sake If you've ever been behind a modern car with bright LEDs I would much rather incorporate that technology in my 40-year-old Z Along with HIDs in the front I don't think you can get any more safer than that. Those 280 tails from klearz look pretty promising I wonder if they fit the profile of the 240 though. Sounds like a fun project Anyway
