Other things you will need is:
- Rear shocks (using ’69 Charger will help locate those)
- Rear leaf spring centering bolts (Again, ’69 Charger will help there as well), ½” size head/nut. The existing leaf spring centering bolts have a larger head (¾”, I think) and a larger nut. Now, a person could take a drill (¾”) and drill the shock plate center hole and differential perch hole larger, but I think the cost of new centering bolts will be cheaper than a ¾” metal cutting drill bit will be (if you can find one).
- Rear brake hose. If a car is over 10 years old and the brake hose you will be working with hasn’t been touched in that time frame, I highly recommend replacing the brake hose, as well. I “think” the metal lines will work with either brake hose – but don’t remember.
The 8¼” differential and 8¾” differential metal brake lines are bent differently – so new lines would be good.
The B-body rear brake hose looks like
And it goes to a 3-way brass block.
The FMJ rear brake hose has the 3-way block built into the hose.
I have never placed the two hoses side by side to see if hoses (with blocks) will interchange or not but I do know the FMJ hose will work.
- 8¾” pinion snubber will be needed and might already come with your new differential.
