I tried it... didnt work for me. I used the Fox brackets, wp and power steering on my 94 with a V1-S trim supercharger kit meant for a foxbody, and it didnt fit. the holes in the fender apron are in the wrong place, lol.
I think the AFM ones are 4". I know the one I fabbed is... haha. The hard part is finding the 90* elbow that goes from the 3" inlet on the blower to the 4" on the piping. most cone style air filters you can get at the parts store have a 4" mouth too.... awesome.
