8.8 rear in a 2000 v-6

cobra irs axle swap into 2001 v6

i have a 2001 mustang v6. will a cobra irs axle bolt in directly? taking a quick glance at the irs, it doesnt seem like many of the components match up.

my other question is: if i get an 8.8 from a gt, can i put my original brakes from the 7.5 and bolt them on directly to the 8.8?

thanks
 
8.8 axle swap

if i swap my 7.5 for an 8.8 can i use the original driveshaft? if so, is there any danger of me installing it "out of phase" to the new rear end?
