Might this help? Here's a collection of spring info from historical forum and email:
"Group, Does any know the part number of the 406/416 front springs described below?
"The optional "heavier" spring has 6.5 coils of 24.5 mm diameter wire. These
have an unloaded height of 300 ± 5 mm, and a loaded height is 126 mm. The
coils are the same nominal 175 mm diameter. This is the spring you will most
often, but not always, find on the CASE MB4/94 as they were normally sold."
"Like everything else with Unimogs, there's more than one. <G>
404 321 01 04, 21.0 + 0.2 mm diameter wire, 6 coils, height unloaded
282.0 mm ± 5.0mm, spring rate 80 N/mm, the common version, or
404 321 00 04, 23.3 ± 0.2 mm diameter wire, 5.75 coils, height unloaded
255.0 mm ± 5.0mm, spring rate 146 N/mm
this is the normal rear spring, used with or without an inner helper spring. It was a special version option for use in the front.
