I am planning to run an 8.8 with disc brakes and all. The difference is 1/2" wider than the A body 8-3/4 I have currently if I remember correctly.
As for the narrowing of the spring location.... excellent point, and aside from a decent sway bar nothing will change the effects you speak of. I am aware of this.
To give a general idea as to the future set up...
8.8 swap (for the disc brakes, limited slip, big bolt pattern,and cheap price that accompanies those items)
Spring relocation kit
7/8" rear sway bar (currently installed)
Possibly a watts link as well.
