I'm still a bit surprised though, as you are. There must be a good 1,000 4CVs in France I'd have thought. I reckon you'd sell several in Australia and we have perhaps a tenth of that number of cars.

I've asked about this exactly in France. To replicate them properly you need some dimensions and spring specifications, a fair bit of work having been done by Gregoire to get them right, and that needs an example to measure up. They are very rare! I asked with a view to maybe getting a batch made professionally - I reckon you could sell them perhaps in the dozens (they won't be cheap). The answer I've had is that the the key component - the top spring housing piece - is a real practical problem being forged aluminium. I'd have thought you could do it in steel but it's out of my league. It would need a design exercise to do it safely.Perhaps it's an I.P. thing but I have always wondered why people don't craft their own Gregoire rear suspension kit.
