What gears with OD A-833?

Seems to be some confusion on all the transmission gear ratio. 833OD 4th is .73 (cars) or .71 (trucks)

All 833 ratio's
"thru midyear 1966 A-body 3.09:1 - 1.92:1 - 1.40:1 - 1:1 = B/RB and LA engines. (These all used a 4.35" IBR.)

1964 thru 1970 B/RB engine 2.66:1 - 1.91:1 - 1.39:1 - 1:1 = (The "close ratio" V8 gearbox)

1970 T/A & AAR 340s 2.47:1 - 1.77:1 - 1.34:1 - 1:1, = 1970 thru 1974 high performance
(A 2.44 first gear was also produced in this time period and some units had 1.91:1 second gears.)

1975 thru 1987 Overdrive 3.09:1 - 1.67:1 - 1:1 - 0.73:1 (Trucks used a 0.71:1 fourth "
