Thanks for the explanations, it does make sense when you think about it. I guess that means the front and rear hydro units are the same and the helper springs compensate for there not being and engine in the back.
Yes, the suspension units are the same.
No! The different ratio of the arms compensate for the weight of the engine. The helper springs stop the car from acting like a see-saw.

Do you know where to get the radius arm bearings? Do I have to get them sent over from UK? Last time I did it I was able to get them from my local bearing shop, but it has since closed.
I would still try a bearing place or give Mini Kingdom or Karcraft a go.
If you are going to rebuild the rear frame it would be a good idea to make it adjustable. You can make a camber adjuster like a Mini one. It would also be a good idea to adjust the toe settings as well.
I suppose you could work on Mini adjustable arms for the front but I would make slot the inner mount for the bottom arm, fit a thick washer on each side, set the camber and then weld the washers to stop the movement. A lot cheaper. When you want to change the camber you have to grind off the washers and go again (a bit of a pain in the arse but how often do you adjust camber anyway!)
