8 3/4 rebuild parts help

Hello FABO friends. I am rebuilding the 8 3/4 axle I got out of a B-Body to install in my A-Body. I tore it down to a bare housing, cause I have to move the spring perches 1/2" in on each side, and I'm gonna rebuild it. Where would you guys suggest I get the parts? I'd like to stay with the standard tapered bearings, and I need new seals and everything. Where is the best place to get a bearing and seal kit? Also, I need new lug studs to get rid of the left hand threads, and also new spring pads with the 1/2" centering hole.

Now for the brakes, I need new drums, shoes, and a drum brake hardware kit (with all the springs and such) and a adjusting kit. Where should I get all the parts at? Brakes are the 10x2.5" I can find some of the parts on rockauto.com.
