Cal - The 289 windscreens were different than most 427's, but having a thickness to verify is certainly valuable. The 289 usually had the reinforcement around the bottom, whereas the "traditional" 427 screen was solid clear (note, there were a couple or few very early comp 427 cars that left SA or were outfitted with the 289 style reinforced screen). I just checked my original 427 screen and it's .133"-.139" thick, depending on where you measure it.
