pero teni los numeros de las transfers? y de la corona? pa calcular bien

Solo esto :
NP 203
Type: Chain-driven, cast-iron
Low-range ratio: 2.00:1
Weight (lbs.): 165= 74 KILOS
Lubricant: 10W-30/10W-40
Length (in.): 21.5
Width (in.): 19.0
Height (in.): 15.0
Used by: Ford, Chevy, and Dodge in all 1971-80 full-size vehicles. Use depended on the year, model, engine, and transmission. It is suitable for V-8 power in trucks with GVWRs of up to 10,000 pounds.
The NP 203 is a "full-time" transfer case; it has a set of differential gears which allow for full-time operation; the differential action can be manually locked out. Kits are available to eliminate the action and convert the 'case to part-time. An NP 203 can be distinguished from a part-time NP 205 by its single-piece rear output housing and shift rail coming out the side of the case.



NP 205
Type: Gear-driven, cast-iron
Low-range ratio: 1.98:1
Weight (lb.): 138 =62KILOS
Lubricant: 80- to 90-weight
Length (in.): 13.0 (GM); 16.0 (IH)
Width (in.): 18.0
Height (in.): 12.0
Used by: 1971-1980 Broncos, Blazers, and Ramchargers (and corresponding full-size pickups); the NP 205 is still used on heavy Dodges. Some Dodge and IH models were longer, "divorce-mounted'' versions. The NP 205 has left- or right-side front outputs and a center rear output. Caution is advised: there were many varieties in NP 205 shaft splines and so forth. A PTO plate can be found on the left side of the 'case.
