B-body leaf springs?

Hey everyone,
Sorry if this question has been asked before (I tried searching). The rear springs on my 5th Ave are shot, and looking around online I saw that speedway motors has "chrysler-type" circle track springs for cheap, in all sorts of spring rates and arches. They say in the description that they fit the b-body. Would it be possible to use these on an fmj by using something like the extended front hanger made for using e-body xhd springs?
