Hello,
I have a 66 charger with a 741 8 3/4, I also have a 8 3/4 out of a 70 charger that has a 489.
I plan on pulling the 741 out, and putting the 489 in its place.
I want to use a clutch type sure grip and plan on 3.73 or 3.55 grear set.
I know the 489 and 741 will swap each other out into either of the rear ends.
My questions are.
What other parts will swap between these two rear ends.
What, if anything, do I need to be aware of with the install of the sure grip, I vaguely remember something about the adjuster and or the axle spacer/button, that goes between the axles?
Is there any advantage of one year over the other, I thought the 66 was 3/4" narrower, so maybe tire selection would be greater , albeit only a little ?
Thanks in advance
