This was recently posted over on the SSR Forums (for those that want more bling): Finned Differential Covers
I'm not sure if it will. I know the T/A cover on the 12 bolt in my Z28....the lock nut and preload screws barely clear the panhard bar(tubular)I just dont know if the T/A cover will clear the rear panhard bar. You may just need to have a custom bar bent to clear it.
I have always been partial to these. The look good....not you you can see it anyway with the spare tire in place.....and actually serve a purpose by preloading the the rear. I have used one with good results on the 12 bolt in my Camaro.
