Well a Datsun 1300/1500 pickup will have an H190 almost exactly the correct width. Maybe $150 all you need to do is grind off the leaf pads, weld on the B310 4-link parts, and adapt the brakes.

Or if you can if find a S110 (Gazelle) bolt-in unit maybe $900? Rare as.

Aww cool thanks yeah i been calling around for s12 h190 and no wreakes have them. I will have a look into the 1300 diffs thanks

S12 gazelle you mean. They aren't bolt in either.
The bottom arm mounts are 10-15 mm out too far so Ideally you would want to remove them and weld them in more so the bushes don't chop out as fast.
Or you could just remove the shock mount and move that to get the shock in the right mounting spot.
I'm about to do this in my stanza, same as sunny b 310

Really. Yeah I have a h165 i think in my sunny but I fear that my motor is going to fri it. As I am going to be running ca18det with t28

I meant S110 (1982-1983). It is a bolt-in for the B310 and has rear disk brakes. At least in Japan/USA.

S110 1980-1981 is a bolt-in H165. Fairly strong and will hold up to stock CA18DET no problem.

Its not really stock lol but I am only planing on having around 230kw max at the wheels

I don't think we got the s 110 here dd that's why we both thought s12.
Looked at wiki and Google and I have NEVER seen one here locally.

S110 Nissan 240RS was talked about a lot on here, but maybe that was race-only and never sold to the public?

CA18DETsunny, did you find a suitable rear axle assembly?
