Your two specs are correct; 44" between centers (oops…"centres") and 2.25" width. Also:

Depth: 1.172"

Laden camber: 0.50" negative (on or off car)

Laden camber load: 165 lbs.
(On car; load to be evenly distributed approx. 20 inches from
center line of rear axle.)

All info shamelessly plagerized from the work shop manual. I cannot be held responsible for any confusion.
