Piñon and Corona relationship

I have a doubt, it turns out that in my country we do not find spare parts for a differential of Nissan Frontier 4x4, only one is achieved with a 37: 7 relationship and the one that is this car is 37: 8, can that differential be used or cannot be used?

mmmm, or says that your differential crown has 37 teeth and the box of cash 7 teeth,
for your consultation the differential crown is the same amount of teeth, where this is the problem is the box output pine nuts that has 8 one more tooth.

Your original gear relationship is 5,285 and
the relationship they sell to you is 4,625.

It should affect the final speed in the fifth change, but for that I need the final ratio of fifth march and the pneumatic measures, to calculate those speeds

There is where the mule boto to Genaro, said of my country when there is something very complicated, the ratio of the fifth gear

Hello, a problem that may arise is whether it has a double differential, that is, one in the front axle and another in the rear and having different relationships will surely be damaged by either of them in the two in the short term. Please verify this before placing a different relationship.
Greetings.
