Nice! It looks like the you have the fabrication skills. Keep the pics and build log coming.
Oh yeah, Welcome!

I've been toying with ths idea for the rear suspension to have just one link shock between the 2 wishbones via a bell crank arrangement. Would save time n weight.
What do you guys think as I have seen it done many times on rc cars etc.

That arrangement will not provide any roll stiffness. You will have to provide all needed roll stiffness with an anti-sway bar or similar.

I am curious about the drive housing on your rear axle. Is there a differential in there? If so, where did you get that assembly?

Yeh I guessed there would be that issue but if the front double wishbones have a spring each it may help the issue some. The rear casing is off a old peoples 24v mobility scooter that are a familiar sight here in the UK.It was shortened to just the diff unit not needing the full transaxle width.
The drive from the motor to the pinion was by a high ratio helical spurs. The axle gear is made from a grade of cast iron that is case hardened . This was no good after I machined a step on it to fit the sprocket as the wall thickness would have been thin causing cracking and poss breakage. I therefore machined a new one from mild steel and machining the diff gears recesses back in as standard. It will be no good as a driftin tool but will turn on lawns etc real well. The UJ's are landrover steering column ones and look to take a fair amount of torque ( pray).

Here's that pic of the original cast iron spur gear with the spigot dia' machined on it.
