What is the correct position of the rear lower shock mount, for a 1950 1/2 ton with tube shocks?

The shock mount bracket, which holds the leaf spring, can be installed 2 different ways.

With the shock post/nut in the "up" or "down" position. This changes the distance of the shock length.

If I use the "up" position and have the correct shock, does it really matter.
