disc brake deal on craigslist, will it work for mine.

so I want my duster to have discs up front, I found a set online for a 72 will they work for my 75 cause drum brakes SUCK! haha

that being said am I better off swapping to BBP rather than stay with SBP i know there are more wheel choices if I go that route. and I beleive that the short ford 9 I have is still ford BP, which is the same as mopar BBP if I have read correctly.... Let me know if I am off base, the help is humbling and helpful thank you.
