NP 208
Type: Chain-driven, aluminum
Low-range ratio: 2.61:1
Weight (lb): 79
Lubricant: ATF
Length (in): 8.0 (GM); 15.5 (AMC)
Width (in.): 20.0
Height (in.): 5.0
Used by: Many full-size vehicles, including Jeep pickups and Wagoneers (which used a left-side front output shaft). A part-time unit that replaced the stronger, heavier NP 203, the NP 208 can't stand up to the horsepower that the NP 205 can, but failure is more often related to low oil level than too much input torque. The 'case utilized left- or right-side front output shafts. All Jeep model 208s have the same spline and output-shaft size and bolt pattern as the Dana 300.

DANA 300
Type: Gear-driven, cast-iron;
aluminum tailhousing
Low-range ratio: 2.61:1
Weight (lb.): 86
Lubricant: 80- to 90-weight
Length (in.): 11.5 (face to center of rear output shaft)
Width (in.): 16.0
Height (in.): 9.0
Used by: All 1980-86 Jeeps. The Dana 300 is similar to a Dana 20 but has a more desirable low-range. It also uses a single lever shifter. The Jeep version uses an entirely different bolt pattern from the Dana 20, while the Scout version (1980), known as the TC-146, uses the same pattern as a Dana 20. The Dana 300 is very adaptable, compact, and strong.

BORG-WARNER 1345
Type: Chain-driven, aluminum
Low-range ratio: 2.72:1
Lubricant: ATF
Length: (in.): 17.25
Width (in.): 23.0
Height: (in.): 12.0
Used by: Some 1980-to-88 full-size Fords. Holds six pints of Dextron II ATF. This unit can be towed extended distances because of its built-in pump that channels oil to all necessary bearings.

BORG-WARNER 1356
Type: Chain-driven, magnesium case
Used by: Recent-model Heavy-Duty Fords; replaced B-W model 1345.

BORG-WARNER 1359
Used by: Two-wheel-drive Fords. Resembles a transfer case, but has no front output shaft or internal gears. The B-W 1359 was probably installed to avoid a separate driveshaft for rare 4x2 Bronco IIs.
