best place to get big brakes?

just past noon here. got a call from gil, a local club guy http://www.moparshawaii.com/
i'm taking a big brake b-body rear end (alotta B's) with 3.20something open case and a 3.91 sure grip on the side off of his hands for 600.00

i'm gonna go get it in a couple hours. good deal ???
hope so bec its hard to find that stuff here, if i dont get it now, i may be waiting a long time before the opportunity comes again.

otherwise, sunny and 85 lol
aloha- pauly
