I got the gmpp one, came with stb and rear for $132, thought it was a hell of a deal seeing autozone wanted 120 just for the doorman front. Come to find out its hollow, and I believe somehow I installed it upside down, cuz its rubbing on on my dp.
Edit: just got done flipping mine so its correct now. Took about 1 1/2 hrs. With hand tools and floor jack.
