Those tires are huge.
You can use springs from tons of Mercs. W124,R129, probably W210 and others. R129 tends to have light springs up front and stiff rears. Here's a W124 spring chart:

Wire diameter is a good indication of rate when spring rate isn't listed.
Don't forget bump stops too. These cars live on the bumpstops, no matter how stiff the springs are.
