The Zthirtytwo part is better. I ordered from conceptz I should have researched more as I thought zthirtytwo. After dissatisfaction and more study I realized the conceptz part is lesser quality. I then bought the zthirtytwo part directly from that website. The vent pins fit and operate better. The overall fit is better. Both required some tweaking of the metal brackets. In the end I was able to get better radio placement with the zthirtytwo brackets also.
