hey guys can anyone help me with the code number of a 1200 ute diff, i have had people tell me its a H160 and others tell me its a H165, how do i tell and what other centres fit, i now have two and want to keep one as a 4.1:1 and need to find about 4.3 to 4.5. thanks Is there a factory type lsd available out of any diff centre that would fit and where can i find one

cmon guys someones gotta be able to tell me the code number!

dont know about the codes, the Wiki has a heap of info on that type of stuff, as well as the various diffs.

As far as LSD centres go, I have herd that Nismo made a few and you can still get them from Japan, but there probably the rarest part around. 'Topgear' is making some LSD centres around mid year, they will be about $1100 i think, I'm getting one for my h165. There is a whole thread on here with info and order list, I will see if I can find it...

Here is the Topgear LSD thread

I think that the utes after 1976 came out with the h165 and I think were 4.1:1, everything before that came out with the h145.

thanks mate, will now have to c if i can find a ratio to suit.
