I just installed it on my 23 double V4, the quad lock dash mount and the crash **** on each side of the engine. The material is excellent. It’s engineered precise very tight tolerances everything kind of goes together the way it should however, the instructional videos are very lacking. There’s no sound. They don’t identify the parts in your left. Guessing you have to check every part to make sure it’s the part that they’re talking about and there was no written instructions.
