Wow thats a crazy find, I did not know that there were any more out there to find. You will want to look in yahoo groups for the "laser 917" group there are a bunch of people there who have information on elite enterprizes and the cars that were produced by them. If its a one off windsheild you might be able to cut something down, but following the design trends of elite you more then likely need a vw bettle front of some kind or cut down glass from a common car.
My first kit was a 917 laser so I am fond of everything that elite built over the years
