Thanks Harald for the pics,Interesting.
I have to agree with keeping the original spring system. The factory are supplying 4 leaf replacement for 2 seaters same price as original 5.
If these leafs are thicker and stronger than originals they may give better ride and handling.
The Aust. Army replaced all the multileaf packs on the series 3 landrovers with thicker 2 leafs springs. This gave better ride plus 30cwt capacity for towing field guns.
