There are blank ones sold on Ebay and a PDF of one here on moparts, but isn't quite right. Once its gone....its gone, unless you find another in the car.

I found the article and its in a May 1992 High Performance Mopar mag. I'd scan it, but my scanner doesn't work anymore. The date on the roof is for GTX's only. It states that on Feb 1st, you could get the V4- 1/2 vinyl roof in green, gold, black or white. V4X being black.
