1987 One Piece Hub Conversion

[1987moose]

Do I have to change the knuckle on my 1987 bronco to convert to the 1980-86 style hubs? Or can I just change the spindle, outer shafts, rotor and hub? A local shop told me that I have to, but I notice the kit that broncograveyard sells doesn't include a knuckle. Do they use a special spindle? Or was the shop feeding me a bunch of bull? Thanks.

axles, spindles, rotors, hubs. Pretty sure that's all i did to convert my '87 to a later model year. freaking '87 was the worst year for all vehicles.
