Flange

H145: scalloped flange, bolt hole rectangle 36 x 50 mm
174_5a58324e15d6b.jpgPost 487206

H150: 45 x 54 mm round or rectangular flange
H165: 45 x 54 mm round or rectangular flange

There are some differences between flanges on H165's, some long (~217.5mm from carrier mounting face to driveshaft flange face), some short (~202.5mm). Depth of hole for centering boss varies also.

H190: 50 x 60 mm, round or rectangular

Axle Codes
H = Hitachi removable gear carrier (pumpkin/centre section)
HA - H145 (145mm diameter ring gear, 5.709 inch)
HB - H150 (150mm diameter ring gear, 5.906 inch)
HC - H165 (165mm diameter ring gear, 6.496 inch)
HD - H190 (190mm diameter ring gear, 7.480 inch) ALUMINUM CARRIER
HE - H190 CAST IRON CARRIER
HF - H190A revised for strength
EXAMPLE: HF38 = H190 with 3.889 ratio was factory fitted

Axle code is on Chassis Identification plate 1980-on, in the engine compartment. Starting in mid-80s, Axle Code is on door-jamb sticker.

Factory LSD has a sticker on the back of the diff housing.

Counting

To verify the ratio in the vehicle matches the original equipment (or build tag), you may count turns of the wheel vs turns of the driveshaft. If slightly less than 4 turns of the driveshaft results in one turn of the wheels, it is a 3.9 ratio. If it takes a bit more than 4 turns, it is a 4.111 ratio.

Even better is to note the stamped numbers on the ring gear. For example, this unit is stamped 39:11
24439.jpgAlbum 24439

39 divided by 11 = 3.545 ratio
