8 3/4 disk vs drums

I recently acquired an original A body 8 3/4 housing for my 71' Scamp. i currently don't have anything else for it but i plan on just ordering new axle shafts for it and have my eye on a couple carriers on craigslist. i have 2 questions first one is would it be easier/cheaper to just throw drums on it or since its pretty dismantled would it be more worth it to convert it to disks? second question, when going with drums again can i get an 8 3/4 from an E or B body and steal brake parts like backing plates, drums, shoes, cables, ect. and put them on the one for my Scamp?
