Lambo tour of North USA beats floating down the Bow River in your +8. They float because they are made of wood so everyone tells us !!
I have replaced the rear springs on my +4 4 seater. I think the chassis is the same but not sure about the back axle. On mine, the spring was located at the front by washers and a tube spacer. I don't think you can change it as the back is bolted straight onto the chassis with washers. Pig to get to the back as it is boxed in with the body over the top.
