newer rear disk brake rear end option??

[michael bustamante]

so as some of you may have noticed i am parting out an '03 yukon xl.
this has a coil spring disk brake 3;73 rear end in good condition and seems to be a lil narrower than the pickups of the same year. now i know id have to change the prop valve and get adaptors for the fittings to the caliper brake lines and change out the mounts, but have any of you gone this route before and how did it work out. Im doing the LS conversion so itd be nice if this went with the conversion
