Ques. 4 Swapping 4th Gen Rear into My 3rd gen

Hey guys i have a few question ive searched but i cant find them i found a rear end from a 95 z28 it was automatic with the lt1, before i buy it i wanted to kno is it going to be a direct bolt on or will i need some misc. parts, mainly the brakes(e-brake line, brake lines) also will my speedo be affected due to different gears im going from a 9bolt borg warner with 3.23

Also if the rear that is going in has 3.23's you'll be fine otherwise you'll need new speedo gears, you can find info on those in the sticky in this forum -
"T-5 drive gears"
