Don’t know of a direct swap over from a disc brake car. Scarbird sells a caliper bracket with instructions-you collect the other parts on the list and do a little machining, BCCP, and Kanter sell a ” turnkey” kit. All of them require a new dual reservoir Master cyl for a disc/drum set up which will require a little to a lot of frame trimming, your orig MC is not up to the job. Do a Search Forum on the bottom of the page for info, and see the 6163skylark forum for more. There are similar options to convert to 5 lug at the same time. Others here and done this as well and will chime in.
