I am curious about swapping my 1989 ZF6 car to the rear knuckle and brake setup including parking emergency brake of the early cars. In particular I believe I would want to use an 86-87 rear knuckle since those have holes for the rear ABS sensors?

Half shafts should bolt right up. Dog bones are the same.

What about the lower camber strut arm rod? Would I swap to the early 84-87 lower strut arm rod, or keep the later 88-96 lower strut arm rod?

Knuckle obviously gets swapped...

What about shock mounting... will the later 88-96 shock bolt to the early knuckle stud mount, but then fix to the upper body frame mount of the later car?

Not sure, but shouldn't you be able to just remove the ABS rings from 88-96 outer stub axles and install it on the early stub axles. Then just swap out the stub axles and brake assembly with the early stub axle and brake assembly?

Does the Knuckle need to be replaced?

Yes the primary goal here is to use the drum style emergency hand brake rear set up on a later 88-96 car.

After thinking more it seems like I would need to use the early 84-87 lower strut camber control arm rod, which means using the earlier 84-87 lower camber strut arm rod to differential bracket...

That would mean switching the later 88-96 rear roll center geometry the earlier, unless I installed the After Dark Speed rear camber strut arm rod and bracket kit...

Okay so assume I install the after dark speed rear camber arm rod and bracket kit... then I just need the earlier knuckle, spindle and yoke, aluminum spacer adapter that houses the emergency brake components, the emergency brake components themselves, the earlier rotor and brake caliper etc... later dogbones should bolt up to the earlier knuckle...

Only thing I still don't understand is the shock... the top mount needs to be later 88-96 style, but the bottom mount point is now the earlier 84-87 knuckle... so do I use a later 88-96 shock? Or do I need a custom shock?

86 versus 96, only difference I can see is the brake mount/spacer (and bolt length, stub axle length with the much wider spacer.)
