I'm not even sure what we're talking about at this point.
Replacing the spring shackles?
Housing floaters (which won't work with the above mentioned) ?
Adjustable uppers are for 4 arm suspensions, not leaf springs.

"Must remain as produced" means stock shackles. There was never a slotted shackle factory produced on a leaf spring car.

AFCO and others make them. They bolt or are welded to the frame rail and the slots allow the rear spring eye to move forward and backward.

They are not legal replacements for shackles in Stock.

No long shackles, short shackles, offset shackles, sliding shackles, in Stock.
Been like that since 1972.

Was just elaborating on my remark that anything bolted on is legal and anything welded on is not regardless of suspension type.
