looks like a simple enough trailing arm setup like the one nat (nsdev) used on his old grasser and is now on his twin bec fiat grasser, check his
archive.
As long as the structure is sound and the pickup points/stresses are worked out correctly and adequately braced I see no reason why it won't
work.

do you think that it will go round corners ok. i was thinking of making them into a v shape to try and make it a bit stronger when you get side ways
froces on them.

body roll will cause camber change in equal degrees, but it will work. Double wishbones let you have more control over the wheel.
You could make a box to bolt to the bottom of the car, with the diff inside it and wishbones mounted to it. Then you just have to cut a hole and stick
some springs on.

id go de dion as well as you can fab the whole lot off the car and offer it up as one unit with the shafts at the right angle and the arms running
slighly downhill at your chosen ride height,thats how i did it on my van

A full trailing arm is ok for FWD cars, and RWD cars where lots of suspension travel and a 'loose' back end is an advantage (e.g. grasser)
but I don't think it would be the best setup for a RWD tarmac car.
A Deidon would certainly be one of the easier options, but you might consider fabricating a subframe to take a double wishbone setup.

ive just had a quick measure and i need the hub faces at 1370mm. ive had a look at the de dion and it looks just like an improvised escort mk2 axle.
and looks easier to make then some things ive been looking at lol. could you chage the size of the tube cause we have no 60mm in stock at work but we
have some 40mm by 4mm thick. ive just bought a new plasma aswell

Difference between a de'dion and a live axle (escort MkII) is the diff and half the driveshafts weight aren't sprung on the de'dion.
