Hello,
I have a 1969 charger 8 3/4, 489 case, rear end, with open differential and 3.91 gears.
I will be putting this under a 66 charger, with a 383 automatic.
I have seen some 481 cases on Craigs list, with sure grips, at some decent prices.
I WILL stay with the 489 and its thicker shaft, so.....
Will a sure grip from a 481 case, install into a 489 case ?
I understand the ring gears and pinions do not interchange because of shaft and bearing size differneces, but I am not sure about the sure grip.
Lastly, what if not a sure grip, what would be recommended for installing in this ?
I have a powertrax locker in my 69 440 4 spd charger, but man is that thing loud and clanky.
Thanks in advance
