In the two runs they've done, they did both WM numbers... in the first plastic frame and lead blob release back in the late 80's, 81 was in Fireball and 82 in speed, the second run was vice versa. I took an old speed shell and put it on a new drive, which took a modicum of effort, but gave pleasing results...
They could do the later speedletter scheme with gold pin strip stopping before the curved side skirt, and if pushed, I'm sure they could do the Chessie re-numbers. (Both of these would be appropriate to have the dual headlight modification)
