Swapping rear ends - drums to disc
I'm sure this is not a new topic/question and the answer(s) is probably in the archives but I'll ask it anyway. The Iroc I just bought needs the fuel pump replaced so I figured I might as well swap the rear in it (GM open 3.23 drum) for the one from my donor/parts car (BW 3.27 posi disc). I know the rears will bolt up just fine but what changes will I need to make to the brake system?

Re: Swapping rear ends - drums to disc
Ok...so I finally had time to look in the archives and, other than swapping the rear end, master cylinder/proportioning valve and parking brake cables from the donor car, I should be all set with parts. Does that sound right or I am I still missing something?
