Im half way through my install, the car is in pieces in my garage and I just realized im missing a mounting piece for my components. I have one of them..but that dosnt do me much good. I don't know what to do, I cant go much further until I have it and this car is my daily driver.

Is it possible to order one of the brackets? Can any shops on here help me out? Im willing to pay whatever for it I just need it this week. Its not the external mounting one, its the one with the 4 tangs you can break off, for inside the door.

I can take pics if needed, please help me.
