Hey guys. In the center of the s5 tranny crossmember, there is some stuff missing on my car (all thats there is a nut) would this cause a clunk in the rear end? Im going to install what went there when I can find it

 

I tried searching and couldnt find this thread that is like 3 weks old. Oh well. Mazda only sells the complete crossmember from Mazdatrix.com

here is mine I made out of delrin in my machine shop class. I would have made more to sell, but class just ended and I ran out of material
