Tried a quick search- no luck: Does weight of wheels really make much of a difference?

Why not run the modern 8 1/4 jeep grand cherokee rear disk brake setup? Don't they charge like a little over a hundred bucks for an axle? Some one here or on moparts converted their 8 3/4 with those brakes if i remember correctly.

Mostly because I got a 8.75 out of a dart in the back, and I don't think think a jeep rear end would be an improvement
