naa not your fault

Yeah I wasn't sure Eaither sorry about that

yea had no idea that there were 2 different types but all way's good to have spares incase i get a sedan :)

Hey maddatter no your wont need to change the axles only the centre.spewing the sedan diff won't work

Ok thanks, will I need to changes the axles aswell??

Yes, the usual source of used parts is the wrecking yard. But you can also buy them from club members, gumtree, etc. Best to buy one straight out of the car, not one that's been out and sitting in the yard for years.

Where can I get a diff centre from? Or do I have to hit up a wrecking yard?

Yes, it is possible. But more reliable and less expensive to swap in a good used H165 center unit. They were used by many Datsuns.

Is it possible to recondition the h165 diff then???

The 1200 sedans and coupe use H145 diffs. The ute's use H165 diffs. The inside diameter of the ute diff. is 20 mm larger, and uses a different housing. So NO you can not use a sedan diff in a ute without changing the whole assembly. Not a smart idea as the ute diff. is also stronger.
