I just spoke with Dan. He has been at the meet a few times. He currently has 4 hatch covers. He also has a mold that he had made. He has 1 acrylic cover that he said is pretty much an exact match to the original. He also has 3 lexan ones He said they are a little lighter in color and have a couple slightly visible air bubbles on the edges from the heat/ vacuum process.
He can have more of either made the company he had do them is still in business and he owns the mold he paid to have made.
He said 225.00 for the acrylic ones and 150 for the lexan ones.
Let me know if anyone is interested in them am I can PM you his number.
