So which 8 3/4 was the better one? 489,741,742? shruggy

Early /6 a-body's? 99% had 7 1/4 rears. My 3 speed /6 Twister has the 489. 741 weakest, 742 then 489 but of those two each has their good and bad points but neither will not hold up behind a 4 speed unless he has 675-14s, they where made with grease I think.
