You'll want to verify axle tube size. The later Caprices & the ones w/the disc set-ups might have smaller axle tubes. Something to verify since most leaf axle pad brackets are 3". I know other housings under cars of the era had smaller diameter tubes; not sure on those.

You're correct on the fact that it could be a poor-mans narrowed housing. There are also lots of others that can fit that need. Knowing the best (closest) width for your wants is the starting point. Measure the distance between the farthest outboard portion of the fender openings where the tires might rub. Factor in the wheel width/back-spacing to determine what rear-end width will work. Google rear end widths for more info & that should help guide your options.
