If you get a diff cut down and your ute is not engineer approved yet the whole diff assembley needs to be approved.
To combat this I used a diff out of a Corolla 30-55 series, They are available in 3.8 , 4.1 , 4.3 ratios so it gives you a chance to experiment with what ratio is best and they only cost about $50.00 - $100.00 and replacement axles $20.00
When my coupe is engineered and on the road I will have a borg warner out of a vp commodore cut down. If you want this done a place called classic restoration in perth can do this. Not cheap though.
The problem is no body ever does this conversion the same. The problems I have encountered are different for others.
For example if I had mounted the motor 10mm closer to the fire wall. I would not have had problems with the steering arms hitting the clutch slave cylinder. And could have mounted the thermo behind the radiator instead of infront of it. And had more room for the intercooler.
There is a company - mad dat I think who will do a exchange cross member. I would probally do this next time.
I love my Datsun and for what I have speant I could have paid cash for a very nice R32 GTR.
In my opinion the R32 looks the best and is great value for money. Except at 15 years old and pre thrashed they cost lots to keep on the road.
For the same money my datsun has a better power to weight ratio and is smaller and lighter. Plus the only thing which is old is the shell. Everything else is refurbished.
The 2 door is quite rare. In WA they rarely come up in the local paper. I have had mine for 5 years and only seen two other examples for sale. (project suitable)
If you do get one. Get one thats complete. Because parts like the chrome trim is bloody hard to find.
