I know I am a Nissan owner and that I am crossing the line coming in here but I need some help

The wife has blown her rear diff in here Jeep Asia Rocksta and I have had a few problems getting a new ring and pinion

, I have been in contact with Kia motors in Korea who made them and after a bit of backwards and forwards I found a new ring and pinion

but its is the last one they have and they want $2000 + freight + GST for it

so I was toying with the idea of putting Hilux axles under it until Rick from 4wd accessories came up with anthor idea which is to put a Blzzard axle under it as it is narrower and I would only have to replace the rear

so I need to know a few things
1) How wide is the axle hub to hub.
2) Is the diff pumkin offset if so which side.
3) How far apart are the spring perches.
4) Doses it come with a 4.33 ratio diff.
If anyone could help I would be greatful as I had to put the road tyres back on mine so the misses could do the shopping

and man it looks stupid with 31" tyres on it

so if I get her shopping cart back up and running my truck can go back to normal
