Just got my 78 back from getting new interior, next step is the rear end. The drive train is a 496bbc with a 400 turbo tranny, about 500 HP; still has the the stock rear end. Any suggestions on what I should throw in such as 10 or 12 bolt, gears, suspension, size of wheels and tires (without tubbing), limited slip or posi? This is what I like to call my Sunday cruising car (of course I drive it more than that though). I wanna be able to cruise, but also have the ability to sh*t n get when I need to. Especially, when a rice burner pulls up revving up his coffee can exhaust.
