The easiest brake upgrade 8 3/4

n8ling said

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??????

No, it wont work. MOPAR did not make a large bolt pattern 8-3/4 for the A body.
Either find new or good used 10 x 1-3/4 drums for the small bolt pattern 8-3/4 and have them drilled to large bolt pattern OR replace the original axles with large bolt pattern axles and complete brake assemblies.
New A body axles with bearings around $300 plus shipping. Used...good luck.
Large bolt pattern 10x2-1/2 complete used rear brake assemblies from any 65 up $100 =/- a few bucks.
If your going with new axles I reccomend contacting DoctorDiff. I bought a set from him last year. Excellent vendor, very knowledgable.
