Leaf Spring Center Pin Spacing?

[KEENO]

Does anyone know the "Center Pin" spacing on the Leaf Springs on our First Generation W250 (4X4)?



OR: "Centerline of Spring" to "Centerline of Spring" (front & rear)



My Manual doesn't seem to have this info:



It does tell me that the Frame Width (Rear) is 37. 68" (inside of metal)



And: 29. 88" (inside of metal) on the front of the frame.



Also: Is "Track" the same as "Wheel Mounting Surface" to "WMS"?



TIA... ... ... ... ... . KEENO
