The easiest brake upgrade 8 3/4

So I've got a 8 3/4 orig to the car 10 x 1 3/4, Have stock sbp axles drilled to lbp green bearings. (I did notice things are a little snug going together, and yes adj pin removed).
My prob is my drums are toast. Really bad! And would need drilled to lbp.
From what I've been reading here..... If I get 73 < backing plates drums lbp axles etc
Will that work. Bolt in and go??????
