Looking into getting 5 stud hubs on the rear!

[Ganty101]

So currently my 69 c10 has 5studs on the front hubs and 6 on the back. For obvious reasons I’d like to match em all up so either all 5 or all 6. Now I’ve seen some rally style alloys on summit and they are 5-stud which make me lean towards 5 but please guys let me know what my options are. Am I best off getting a conversion kit for the rear drums to put discs in? What info do you need to give me good advice? I know that I have a 411 ratio rear axle option number 4ho4dr.
