Hemi 4 speed

It is likely a long shaft box which is not really what you want in an A

"Generally" the hemi boxes have a little higher geared 1st gear than the 23 spline boxes, I never found it much of a bother, although it was "a bit hard on clutch" when I towed a car loaded to the gills from San Diego to N Idaho in 74-discharged from the Navy

The bolt pattern is the same as any other A833, but the front bearing retainer is likely larger. "Way back in the day" I swapped a junkyard, low miles 340 into my 70 440-6RR and had the bell turned in a lathe to enlarge the center hole.
