1966 Barracuda Reproduction Tachometer - any experience

I removed a factory tach in my 66 Barracuda and bought one from Vans LLC. Works great. Needle is a bit off (size)from the factory tach. I sold my tach and the “box” that controls it because it would not work with HEI or Mopar electronic. That’s a points only unit. Other than that the fit and finish is good. Not 66’ barracuda perfect but so close a Chevy guy cannot tell the difference. lol!
