i think john taylor is the guy from one of the pedders down in nsw....
he makes up the leaf springs for the rear which are supposed to work quite well without any tramp......

BAD310,
Good luck getting the 4 link engineered in QLD, Have you had the design approved by QLD transport yet?? if so i would love to see the application and approval for my own project (save a bit of paperwork).

Engineers in QLD can not approve rear suspension design and a 4 link conversion fits into that category. Once the design is approved by QLD transport the engineer can approve the modification in accordance with the design.

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

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

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

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.

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

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.

looks the same as a stanza 4 link with coil springs

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