Well......one step forward and two steps back. There is a hole in the subframe but it is only a 1/4" and it is centered......don't know if it is there for a center brace....would have thought it would have been larger if it was, more like a 5/16". That smaller hole got me to thinking again so I called the original owner of the car and asked him if he remembered the spoiler on the car and what it looked like. He said that for sure it didn't have any braces on it and that it hung down about 5 " and it had a rough texture. Well to me that sounds like the first design spoiler....so I guess I am back to getting the first design unless someone comes up with any new evidence.
Again....thanks for every ones input.
