are the coil buckets and control arm brackets in the correct orientation for a ZJ? If so then that is a killer deal. If not then I can get the housings all day long with some form of coil buckets and CA brackets for $40. many lincolns had this setup, but the brackets aren't in useful positions usually
Also-
You should be able to drill your old backing plates for the ford 9". Only hangup might be if the center hole isn't big enough for the bearing to pass through. If not I'll just bore that out. Should be no big deal
