[84GT350-1]

I am looking to narrow an 8.8 for use in my 89 coupe and retain the stock four link setup. I also want to use the Moser 9" ends instead of the C-clip eliminators and use a deeper wheel(3.5" back space). Moser has to cut the housing for the the new ends anyway so I figured it could be narrowed some. Has anyone done this or have any ideas or advice. Thanks....
