bad310 so basically you just had the r31 diff shortened to suit then the original sunny mounts transfered to the r31 diff?

oh and are all r31 diffs 28 spline or is there a special one?

Stanza is 1 inch wider overall than the sunny diff, but yeah they are a pretty easy swap. I did that swap on my first sunny.

you can swap stanza and sunny rear ends. yes that is 4link.

looks the same as a stanza 4 link with coil springs

Sorry BAD310 you are probably ok.
I'm not sure if the 310 has a 4 link or not.
If you are connecting the suspension members up to the original mounts then you should be ok. I had a brain fart and thought you were converting from Leaf spring to 4 link.

i dont know what the 310 suspension looks like, but if it has two trailing arms that run where a leaf spring would, and two diagonal arms running from the diff to the body then its a four link. I believe a two link is accompanied by a panhard rod??? take a photo, if it has four 'links' its a four link tho

Is there anybody out there who can verify if a standard B310 sedan's diff setup is a 4link or a 2link and what the difference is between them?
I don't want to go around telling people that it is a 4link and it's not.

thats a good point... I was told it was a 2-link, and thats where my knowledge ends

I always thought it was a four link because it has the four trailing arms, so what makes it a 2 link?
You learn something new everyday

correct me if I'm wrong but BAD310's looks like its set up for a standard B310 2-link rear...
