Bought another Hemi 4 speed listed as a 833

No...the 18 spline boxes were standard equipment for all 440-4bbl cars along with the Dana rear ends.

Disagree, I bought a 72 New Yorker for the driveline, though automatic, 8-3/4 rear.
What I`ve gathered from the years reading this site was that automatics got the 8-3/4 and only 6pac 440s got the Dana and hemi box. but if you say so...
