I have 2 MSD dis 4 boxes and 4 tach adapters. One is new the other was on a car for about 2 months. All the tach adapters are brand new. I was going to use this for a two step on my car but i'm getting rid of the turbo set up so i no longer need them. All of this stuff retails for around 1000 new. I'm looking to get 550 + shipping.
