Stockers work fine. You just have to trim the centerbolt supports back on on side, or simply crimp them flat.

I tried to do the trimming and it never worked for me. I ended up using 2 thick cork gaskets and has been fine for the past couple years. The trimming or crimping works for most, but my GMPP 1.6 are a little different.

The bottom of this link shows you how to cut the braces. Don't cut the wrong side.

I have the cheap autozone ones they are spectre chrome ones. I hope they will worrk. My car is very clean under the hood so i would hate too put those ugly stock covers back on.

Proform 141-131 for black, 141-130 for polished. These are slightly taller and require a little grinding on the alt. I've ran the black ones for the last 9 years, leave out the baffles.
