Finding suspension height

[wobbygong]

My newly acquired old zooka needs new rear springs.

The springs I've seen advertised are either standard height or 50mm higher. For most purposes I suppose that the rear springs should be about the same height as the front ones. The trouble is that I dont know how to tell if the front springs are standard height or not. So I am not sure which type to get to put on the back.

Does anyone know what kind of measurement you can take to see how far the suspension has been raised (or otherwise)?
thanks

Stock springs are designed to ride flat. If there is any curve to them (smilie face curve, not frowny) then they are aftermarket or non-stock. The have a friend sit in the rear of the vehicle (to simulate cargo) to see the flex out back.

Many thanks for the help Billjohn.
I looked at the rearsprings again and the shape is slightly curved (smiley) except for the middle where it curves in the opposite direction... a sort of moustache shape.
The front does look higher than the rear but this might be because the rear springs are stuffed. Theres about 80mm (3") between the rubber bumpstop and the front axle housing. I read in a recent post that this distance should be about 1" on with the standard suspension. If that is the case then it suggests to me that the suspension is in fact 2" (50mm) higher.
The problem is that because I live out in the country i have to order them (springs) in and Im worried that Ill get the wrong ones. Which would be a major pain in the proverbial place .

From the description of the rears, I would say you have a set of 2" Old Man Emu aftermarket springs (standard, not HD). They are known for their strange bow, but they are a good spring.

Sounds good. Unfortunately one of the rear spring leaves is broken in two. I think I'll try to replace them with the same type of Old Man Emu springs.
thanks again i appreciate your help
cheers
