This is the rolling chassis we have got to work with.
This is the mock-up.
The rear single wheel conversion uses the original axle with both suspension arms removed and a bike style swinging arm mounted on it.
A basic "A" frame is bolted to the chassis and a coil-over shock links the two together making the rear suspension a very simple unit. Not only is it simple but it can be fully adjustable and it also means the chassis remains unaltered unlike the Lomax 223 conversions which require one chassis leg to be cut-off.
The front suspension will also be coil-over style as this eliminates the notoriously soft rolling suspension the original 2CV's were known for.
