I will preface this by saying that I am a friend of Matt's and I live near FoxResto's shop. So I am biased.

So now that is out of the way. I stopped by there today and Matt showed me their new 140MPH speedometers for 1983-1986. They take your 85 MPH core and sand blast it (so this is NOT just an overlay that some others offer) and print a new 140MPH face on it and completely restore the needles and mechanism and calibrate it for 140MPH. It looks 100% OEM. They are amazing. If you have been hoarding the 140MPH Motorsports speedos (I have 2 myself) the market has just bombed out, LOL. Check their website out for details. They are $160 essentially depending on what you do.

This is the first release. They will also be doing a 79-82 in Green with the correct fonts and a 170MPH unit for the 87-93 models.
